1991 Mustang Convertible Engine Other

Engine is a 5.0. Just recently I have been adding radator fluid every so often with no visible leaks any where in the system. When starting the car it will run rough with white smoke coming out of the exhaust, after car warms up to normal there is no smoke or very little coming out of the exhaust, could I have blown the lower intake gasket what do you think.

1980 F+150 Pick+up Engine Other

I am restoring a 1965 Mustang. I bought an engine which is an 80's model 302. I believe by the code numbers it came from a truck. The oil dipstick is on the drivers side rear of the block. Will I need to change the oil pan and oil pick up tube to make it work on the mustang or will it work as is. If I have to change it can I put a different oil pan on change type of oil pick up tube and use a timing cover that has the oil dipstick in the timing cover and plug the hole in the rear where the oil dipstick used to go? I know The block also has the fuel pump bolted to the block and not connected to the timing cover.

1993 F+150 Pick+up Engine Upgrade

I have a 1993 F150 4x4 with a 5.0L. I would like to replace with a new 5.0L motor, but with a more aggresive cam for more power, but I have been told the computer will starve the new motor of fuel and air causing damage to the new motor, is this true and is my only option a stock replacement motor, or
can I modify or replace the computer?

1995 Contour Engine Other

about a week ago I noticed after starting my 1995 Ford Contour that my speedometer didn't work and the car was running with a hiccup-like symptoms especially when I was decreasing speed and actually when the speed was getting lower than 30-20 mph sometimes the engine would shut down. A friend told me, since it happen all at once (speedometer and running rough) that it might be related to the speedometer and speed sensor. I'm not a mechanic but I try to look at the engine and see if there was any obvious problem, and I noticed that a cable close to where the speedometer is whas broken. I just dropped the car to a mechanic that works from home to fix the cable, but Would you think that the problem with the car running rough could be related to the speedometer cable being broken? or could it be something else??

I appreciate any help I can get.

1994 Thunderbird Engine Overheating

Hello, We have a 1994 Ford T-Bird LX w/3.8L. When the engine is started from cold - warm-up is normal and heat would enter the passenger cabin. Last week, all of a sudden, about 10 miles into a trip, simultaneously the temperature gauge would peg high, the check engine light would illuminate, the radiator fan would stop and the heat to the passenger cabin would go cold... A few minute later the temp gauge would fluctuate, the check engine light would go on and off, the heat would not return and the radiator fan would work occassionally but not normally. Fortunatly, or not, this occurs continuously.

Things done so far:

Flushed cooling system and new anti-freeze - vented engine during filling and top-off to rid the air trap.

Replaced thermostat.

Tested coolant temperature sensor in cold --> hot water with ohm meter - 57K cold and ~2K hot with nice linear meter readings.

Repaired a hose leak at the overflow tank.

Also, there is single wire sensor on the cabin heater hose from the engine to the firewall - what is this sensor - resembles the temperature gauge sensor at the thermostat.

Thank you for your time and help. - Lee

Brooke Frame 1994 Probe Engine Stalling My car stalls while driving - usually 10 or 15 minutes into the drive, about 70% of the time. When driving the same route, it frequently stalls at roughly the same distance, but not always. Doesn't matter what speed or I can be stopped at a light (however, I've been avoiding driving anywhere over 60 km). Stalls once, can sometimes restart while still in motion, but now have to pull over and restart. Was only happening once per trip, but in the last two days it stalls two or three times in a row within a minute of each stall. Sometimes it idles rough, too. My mechanic has done three diagnostics and there are no codes coming up and he is totally baffled. Replaced the battery as it was showing low voltage, but did not fix the problem. However, it did stop occasional whining I was from the alternator belt when starting up, so I don't know if it's related to the stalling problem. Can you give me any clues what to look at?

I have changed the gauge sensor, ECT, flushed and visually inspected the radiator, cleaned debris from between condenser and radiator, changed thermostat (twice!) and checked AllData. They mention a cooling fan control switch that feeds the PCM (engine f/i computer) I have checked the relays and substituted known good relays. What am I missing??? Where is the fan control switch located? Darned if I can find it! Have one coming from Ford but... not sure it they knew what they were ordering. Seemed to be a new guy.

1994 Explorer Engine Leaking

My Explorer's coolant system was neglected and within the last 6 months have replaced the thermostat, thermostat housing, all hoses, heater control valve, water pump and radiator cap. The water pump and thermostat were replaced yesterday due to a heavy leak from the water pump and thermostat area. Upon refilling with coolant, it seemed I still had the same leak. I have now realized that it's not coming from either component, but appears to be coming from the engine block itself, although I haven't been able to pinpoint the leak due to parts obstructing my vision. Could it be the "core plugs" or "freeze plugs" that are now leaking? If so, where can I find them?
Any help is greatly appreciated.

1991 Escort Engine Lagging

91 escort GT 1.8 manual I have had this car for 4 months. When I first got it I replaced the EGO sensor(the wire was broke off), spark plugs, roter, cap and wires. It ran fine except when starting you had to crank it over more than normal. It did this before I bought the car. The car ran fine so I left it alone. 2 days ago, when I left for work I noticed It was pinging. As soon as you give it gas it pings, even at idle when you blip the throttle. At about 3000 rpm up it has no power.The idle is a little rough too. It also ran very hot on the highway. When I got home, I checked the timing(right on the money)-ran a compresion test(all with in 5pnds of 175pnds and no leak down) and replaced fuel filter. I have a fuel pressure gauge But there is no schrader fitting and no rubber hose for a tee fitting. I grounded fuel pump on the data link and the pump is working. I also looked for vacumn leaks-Nothing. I pulled the spark plugs and they are white with tiny brown spots- Lean? I ran diagnostics, and it gave me a 02-No crankshaft pin sensor signal And 15-EGOS voltage stays below.55volts (lean). Since the sensor is in the distributer, I replaced it, cleared the codes and it still runs the same. I ran another diagnstic and have no trouble codes? At this point I don't know what to do next. Any information you could offer would be Great. Thank you for your time!

Cleared codes and truck ran fine up until 2 weeks ago and the light came on again. Brought it back to my freind and he scanned it again. Reads bad oxygen sensors. What could be causing these codes? If "a" sensor is bad can I isolate the bad sensor out of 3 of them without replacing all 3? I'm pretty handy with a VOM if that helps. By the way, it still performs well even with the lit light.

1989 Bronco II Engine Failing

The clutch has been chugging and making noises when the clutch was in. A mechanic somehow fixed it and said i need to have the cluch pushed all the time and in the future would need a new clutch plate. It was running fine until today when I went out and tried to start it. The truck buckled a little and then the clutch fell flat against the board. I checked the clutch fluid and was just just about empty. I filled it up with brake fluid and the clutch came back up off the floor. The problem is now the pressure is weak and it acts like it isnt pushing the hydrolics. I am unable to shift into any gears. Any advice. Could be air in the lines, but I first pumped the cluch a few times with the new fluid in with the top off to oush the air out, then refilled. Not sure if its the slave cylinder or if theres air in the lines. If so, how would I go about bleeding it or checking?

1997 Taurus Engine Malfunction

Hey, I have a Taurus SHO. I'm thinking there might be a problem with the PCM. The check engine light keeps coming on. Everytime it does, there is a different code from the Snap-On scanner. I'm a mechanic, yet I can't figure this one out. I've always just replaced the part that the scanner/computer said was malfunctioning. The CE light would go off, then come on a short time later with a different code/problem.

So far, I've been through 3 of 8 new ignition coil (CPP), a new EGR valve, new EGR valve sensor, new ECT sensor, 2 new alternators, a few relays, and now supposedly the IMRC is stuck open and there is a problem with the SAI circuit (low voltage). Do you think a PCM would take care of the problem? The car is awesome, but I'm ready to dump it and take a HUGE loss, unless someone can help me.

1992 Bronco Engine Malfunction

Hey guys- really appreciate your time. I do the same on insurance stuff, spread the knowledge! 92 motor in an 87 frame, EFI, Eddie Bauer edition. Trying to trouble shoot a reving problem. For one- Idle keeps going up & down on it's own, not much but enough to say something isn't right. Replaced the throttle position sensor (you go girl!). Worked ok for a month. Now, when the engine gets warm, it goes to a very high rev state at idle- like 2500. And it's still not maintaining a steady idle, grr. Replaced the EGR & coil. 92 motor in an 87 frame, one step down from the biggest motor in it, 4wd w/lockouts. Think maybe the throttle sensor is cracked and/or not properly positioned? Or anything else you can suggest that would cause a slight up down in rev to not carry a steady idle. Oil pressure also likes to run on the low side, will check the oil pump pickup screen. It also has a transmission kickback thing- if you let up off the accelerator at 40mph -60 mph or so, the engine/trans sort of kicks back, like it goes down a gear in the trans before it really needs to. Hard to explain. Appreciate any advise pertaining to similiar bronco issues

1996 Aerostar Engine Chugging

The CHECK ENGINE light has been on for a while now. Three of the codes point to the emission system, and one to a misfire in cylinder four. After the engine gets warm, and I slow down or stop, when I accelerate the van seems to shudder and vibrate and seems to have no power - I guess you could say the engine is chugging. If I try to accelerate too quickly, the vibration gets worse and the CHECK ENGINE light flashes on and off. I can accelerate slowly and once I get above 50 mph, the van runs fine. I don't know if I have an engine air problem, fuel problem, transmission problem, or what. I have replaced the IDLE AIR CONTROL VVE and the MASS AIR FLOW SENSOR since on my previous 1995 Aerostar those parts were often a problem. Any ideas? I can't afford to take it to a Ford dealer, my favorite garage can't fit me in until next week, and they don't do transmissions, so I'm not sure which shop to take it to. Thanks.

1995 Aerostar Engine Chugging

4.0 AWD with 140k miles. Started about 20K miles ago and just gets worse every summer. After engine is turned off hot, is seems loaded up on restart for a minute or two(unless is sits for about 2-3 hours). If the weather is normal or cool there is never a problem. Exact same thing happened on my other Aerostar at about the same mileage. Can't say for sure, but it could be a tad worse with gasahol.

1985 F+150 Pick+up Engine Malfunction

17 year old daughter is doing 80% of the work to repair her pickup, which she rolled two years ago. She's got it running, almost ready to re-paint. Good lesson for her! BUT: it backfires on start, dies on corners, misses horribly, etc. Partial solution, we seem to have lost a vacuum line or two over the last couple of years. Plug stuff with your finger and it runs much better!!

Where can I get a really good diagram for her vacuum lines? Our manual and the engine sticker are worse than useless, especially since there's another sticker saying there's been emission modifications due to a recall (before we bought the truck). The main culprit seems to be a sort of vacuum-line-manifold with multiple lines underneath the carburetor. Found one end for a missing line on the manifold (don't know what else to call it--can't find it in our book) but can't find where the other end is supposed to go.

2000 F+150 Pick+up Engine Hesitating

I have a 4.2 V6. When driving over 35mph the engine lurches trying to maintain a steady speed. It's usually fine after a cold start until it warms up. I thought it was the transmission slipping, because it was a sudden lurching almost, but it checked out okay. It does a little better when I turn off the O/D. When idling at a signal it struggles and almost sounds like it's about it stall. If I take it out of drive into P or N it settles down; otherwise the whole vehicle shudders with the engine.

I just replaced the air filter and used one of those fuel system treatments, but I think I bought snake oil.

We have a 95 Tbird with a 4.6L V8. The check engine light keeps coming on. We have had all four oxygen sensors changed within a 3 month period. SPark plugs and wires were changed last year and the EGR valve replaced. The engine runs smoothly and idles fine. We also had the coolant temp sensor replaced. The mechanic said that according to the code, the engine was running lean. We would cancel it out by disconnecting the NEG battery terminal and in about a week, the check engine light would come back on. We checked for vaccum leaks but found none. Any idea why that light still comes on even when there is no apparent change in the cars starting or driving ?

I heard several years ago that you could short out the port where they plug in the diagnostic computer and the lights would blink in a pattern to indicate the problem.

Next day wouldn't start, found reference to TPS being a potential problem since no Chk Eng light.
Auto-Zone has analyzer for 96 on, not 95 so got TPS and installed. It started right up and it ran fine for a minute before being shut-off.
Next day plugged the old TPS in and it started, but not immediately, and then died (proves it was the TPS, right?). Reinstalled the TPS and it won't start.
On my 81 Chev the "analyzer" plug could have 2 pins jumped and it would blink a code, anything like that for 95 Windstar? This a typical failure?

The car is a Turbo Coup. When the engine warms up to a certain temperature- maybe 100 or 120 degrees or so- it misfires for about 2 minutes wheather driving or parked. If accelerating, it is undrivable and I must pull off the road till it warms up a little more. Then it is good until the engine completely cools down again. I replaced the TFI module and oxygen sensor but there was no change. I took it to a Ford dealer and they said it would stall during the diagnostic test and that they wouldn't do any more before replacing all parts that didn't say FORD on them including the TFI, coil and stator assembly. Looking through the old receipts from the former owner, I found that the same dealer had replaced all of these parts for the same complaint in Nov. 1999. This seems to be a common problem because I see ads for cheap Turbo Coupes with the same problem.

Check engine light goes on/off and engine looses power. No response pushing the pedal until downshift kicks in. Problem occurs after driving for 3-4 hours at highway speeds with transmission downshifting, when going up hills for example. Is okay driving all day when not having to downshift.

The ignition timing seems like it is retarding and advancing incorrectly on its own. Once the problem starts, continues even in stop and go driving. Have to really punch the accelarator to get going. Switching the engine off for about 10 minutes usually corrects the problem.

Will "pop" through the exhaust if given modest amount of throttle but if very lightly given throtle will only buck or almost stall. After, the car seems fine after the mild buck or pop and performs normally. Does not SEEM to happen if car is driven every 8 or so hours. Changed fuel filter, injectors, and plugs - no help. Engine Modifications thus far - 2.5 cat back, Hypertech programer (problem with or without program installed), Steeda timming adjuster (problem with and without any adjustment) cold air kit/k&n, C&L maf meter, C&L upper plenum, batery trunk mounted, 180 temp stat. 65, 000 miles had problem since about 12, 000 miles with no engine modifications and just now is getting more often. Thanks.

1995 Probe Engine Making Noise

Engine has 80K miles on it. Makes tapping noise when cold, but the sound goes away after about 10 minutes. Recently though, tapping can still be heard very slightly. Don't think it is a valve-tap. Could it be a cracked manifold or manifold studs? Thanks.

1989 Aerostar Engine Malfunction

Engine idle sometimes goes up and down when in gear and brakes are applied. Engine does not backfire or hessitate when the van is moving. There is no black or white smoke coming out the exhaust. Engine does not stall. Idle does not go up or down when transmission is in park. Engine trouble light does not turn on until i make a turn, then the engine trouble light comes on. This change in idle speed happens about twice a day. Engine trouble light turns on after about 10 minutes of driving, and it turns on after making a turn? There is a small coolant leak in one of the radiator hoses, but i keep the coolant level at the correct level. The van does not overheat even when it is used in traffic for about 40 minutes. The van has no problems with accelerating or decelerating or bad fuel economy. Van has no problems in starting up cold every morning, it always starts on the firt try. Van has also passed the arizona emissions inspections.

Is there a possibility of a sensor going bad which causes the idle to sometimes vary? If so, which one is going bad.

The engine trouble light coming on with no change in the vans performance is strange. Engine light does not come on when the idle varies. Seems to be two separate items going on with the van. Idle varies but engine light does not turn on and engine light turns on and idle does not vary?

1993 E+150 Engine Malfunction

Hi guys
I own a 1993 e150 with a 5.0 engine and 80, 000 miles.On my back from Fla.doing about 75 mph going up a slight incline the van started to vibrate a lot, would not maintain steady mph, temp started to rise to 3/4 reading. If I let off the gas and accelerate again it runs ok for a while and it starts again.
I brought it to a trans shop and they told me the overdrive converter and overdrive clutch was not working correctly. Since this happens when o-d is working I had the unit rebuilt and a new converter installed but the problem is still there.It feels like a few cylinders are not working, so I pulled the plugs and found the insulators white and blistered. I checked fuel pressure and it is good, and I was able to brake rev it and the problem came in fuel pressure stayed the same. I hooked up a snap-on scanner and it will only read codes no data, no codes found. I put on a vac gauge and it reads ok but no more brake revving, it strains it too much. I think it is a ctc-converter problem but can't figure out why it comes and goes. Any input is greatly appricated. Thank you

1989 Mustang Engine Chugging

waking car up from 5 year nap. Engine is a rebuild with only 28, 000. have installed new plugs. is getting air. removed gas tank and dumped old gas. fuel pump is working. exhaust not a problem. Even dumped fuel system cleaner in it. New battery. Problem: when you can get it to start it will set there and chug. Eventually you can give it enough gas to get the RPM, s up and it sounds great then you let it back down to an idle and it will run good and then for no apparent reason start to chug and die. Then won't start again until turned over several times. seems to be getting fire. looked at vaccum for leaks(none that are obvious. Hope this is enough info. Got a suggestion??

1995 Mustang Engine Overheating

I have a 1995 Mustang with a 3.8 L and manual transmission. Six months or a year ago, the radiator was replaced because of a leak. Recently, I have noticed an odor of antifreeze outside the car after driving. The radiator appears to stay full, but the reservoir requires frequent filling. The temperature guage fluctuates wildly and the climate control never heats up appreciably. I have not noticed cloudiness in the oil, nor do I see white exhaust while at speed. I am a "shade tree mechanic." I have bought a thermostat under a hunch. If it does prove to be this, could you advise me as to the installation. Thanks in advance.

engine lt came on and ford dealer computer showed 2 sensors bad and was replaced. Prior to replacing while driving even pace car would start acting like it was goint to die/almost like running out of gas then after a minute or so continued driving it would be ok. sensors helped a wk or so and started again took to garage he looked at cooling sensor it was fine. he replaced fuel filter and spark plugs which needed replacing; drove about a wk and it is starting again. It is like it starts missing. I put 93 oct in it a few times prior to these episodes; brakes need rotors and pads bad; also before the above events I thought I smelled something different coming thru vents where air cond like a coolant smell/also on 2 occassions car warm once and cool once after going in store and back out upon starting smoke has come out from under front part of hood/When you get started driving it is fine again.

1994 Mustang GT Engine Vibration

My son's 1994 Mustang GT, 5.0, 5spd., has a "horrible entire car shaking vibration" at all rpm ranges, esp. 1000 rpm. (once, the idle dropped down and it smoothed out for a "split second") Problem started when he started it up, prior it was okay. He had installed a performance chip in the intake, which we pulled out, and problem still exists. Had Ford recalibrate the computer, no change, they said it was plugs. I changed plugs, ck'd. plug wires, no change. Had an expert mechanic check it, and said it appeared to be a clutch problem/vibration. I pulled the flywheel and clutch and cannot find any visible problems. (I forgot to mark the flywheel and I read the 5.0 is externally balanced, will be a problem when I re-install the flywheel?) I am having the flywheel resurfaced & balance ck'd., (or should I replace the flywheel?) replacing the pressure place, disc, throw-out bearing, pilot shaft bushing. The mechanic said the harmonic balancer appeared okay, but could the key have sheared and locked the balancer off center as a possiblity? When I get the clutch replaced and the problem still exists, what then? Engine problem? Will appreciate your help.

My 4.0L Explorer surges when the RPM's are higher than idle. It will do this if you try to hold the RPM at any steady RPM for example 1500 in park. When you are driving it is most noticable when excelerating. I scanned it and replaced the EGR position sensor which cleared the check engine light. There was a memmory code 157 so I replaced the MAF sensor. I have replaced the TPS, CKS, IAC. I installed a fuel pressure guage and it holds steady at 30 psi, when I remove the pressure regulator vacum hose the pressure goes to 40 psi.

I got a f150 300 that runs great and it was given to me and ever since i got it it has a very slight pinging noise.. the truck Runs great.. I did an oil change and then had to replace pump(which i think may have been bad)the reason i say that is because while replacing the pump the old filter which had about 50 miles on it was filled with choke cherry pits from a tree and i am guessing from a mouse i seen running around inside the interior right after i got the truck...i replaced the pump and found the same thing in the oil pan..cleaned it out replaced the pump..still has a pinging noise so i changed the oil and filter again and this time went with a 15/40 oil and when i replaced the filter again more cherry pits plugging holes in filter...my question is how do i clean this out and do you think the bearings are bad(there was no metal shavings in the oil pan just choke cherry pits....any suggestions you can give would be great the truck has 87, 000 miles and i am at my wits end...please help!

Hello from B.C.Canada

My bronco has a rebuilt 351m with about 45, 000 kms. It runs fine until recently it started loosing rpms while idling at a stop in drive.The rpms drop erratically from 700 to 400 approx.It will stop if I put it in neutral or park.Also check engine light flashs in colder weather about 5 times pause and 5 more until it is warmed up.It does this some days and others it doesnt.
I have taken it to a shop that I deal with occasionally, they anaylized it for an hour while it was doing this the whole time and got no codes.
They cleaned the I.A.C. motor & passage and even ordered a new one to try it but it didnt stop the problem.

They said they dont know what it was and it could take hours or days to find it but I wasnt about to play that game at 75 an hour.

I recently changed the plugs, wires & fuel filter, and have tried different brands of fuel to see if it was bad gas still no luck.

I have had this problem now for about 2and a half months even though the truck runs excellent any other time. I have to drive 1100 kms in the next month and would like to solve this once and for all. Any help would be greatly appreciated,

Now the weather is cold here and the Explorer is having trouble starting with temperatures under 30 degrees. i have a car starter for it and the car will start for about 30-45 seconds and run at about 2000rpm then hover around 500 rpm then stall out. even when i start it i need to feather the gas pedal so it warms up a lil bit. I have used Heet dry gas on 2 tank refills and fuel injector cleaner. I am lost now. I went to Auto Zone and they hooked the comp up and they had a reading of "bank 1 and 2 running lean". I am not sure what that means or i am not sure he had any idea. After the explorer is started and i shut it down then it will start right up without any hesitations til the engine gets cold.

Got it started with starting fluid and it ran fine and would restart once warm but again with hesitation. So I pulled out the new oxygen sensor and put back in the old one.

1999 Escort Engine Making Noise

This noise seems to be comming from the valvetrain, I took the valve cover off, pulled the rockers - checked trunions and rockers for wear and cracks, no problems found. Pulled the lifters, checked for wear and "flat" spots on the rollers. Nothing seemed bad. None of the valve springs were broken. But under a no load condition (car sitting in park) or going into passing gear it makes a terrible clatter/rattle that seems to be comming from the top end mostly between #3 and #4. It's getting progressively worse and I can't seem to figure out what it could be. The car runs perfectly fine except for this problem and I don't want it to get any worse. Any ideas on what could cause this noise without any broken or worn parts?

1993 Escort Engine Making Noise

Makes a ticking noise coming from cylinders #3 and possibly #4, but only when engine has warmed up. Absolutely no noise when engine is cold. I replaced all 4 fuel injectors, replaced all 8 roller lifters, inspected rocker arms and moved them from original position to a new cylinder (eg.. rockers from #4 moved to #2 cylinder). Compression tests from cylinders are:
____#1 __#2 ___#3___#4
COLD 160 170 170 180
HOT 175 180 170 190

Engine often misses, sputters and jerks when engine has idled for a while and then driven. Once driving down the road, and the engine starts to cool down, it no longer sputters and misses, but still makes ticking noise. Rate of ticking seems to be related to the RPM of the engine.

After a lot of testing, inspection, and replacing parts, the engine STOPPED making the ticking noise for approximately 100 miles. Hot or cold, it didn't tick. Thinking it may have gone away, and it was possibly carbon build up, I Added some Chevron Techron Fuel system cleaner at 1/2 tank and filled the tank with 91 octane at a local gas station. I started the engine and within 30 seconds, the tick came back and continues ticking like it did before. I have also replaced the spark plugs, wires, pcv valve with no effect.

My car initially had a limiter at 110mph and that was removed when i purchase the superchip for my car.

Recently I had a head gasket blow. After the vehicle was fixed and three thermostats later I still have a problem.

1) The heater does not seem to blow as hot anymore.
2) When driving or sitting still the temperature changes from the "O" in NORM to the "A" then goes to completely cold.
3) Whenever number 2 above happens the air blowing from the heater even turns cold.

This continually happens. I returned to the mechanic and he said he could not find any problems. I installed a new radiator prior to the head gasket blowing and have changed the thermostat several times since. He said that I have a good flow and that the engine is at normal operating temperature. If this can be explained I would be greatly appreciative.
