Firebird - Pontiac :: 1992 Will Not Stay On / Idle Rough And Die Out
I have been having some recent issues with my 92 bird lately. It started minor but now the car will not stay on. It originally started out as I would need to press the gas to get it to start and it would stay on, but now if I let my foot off the gas for anything it will just idle rough and die out. I took it into a shop and they said that I had a bad idle control valve and the pigtails need to be replaced. They also said that some wires were shorted out and they would replace those as well. They replaced the Pigtails and the idle control valve and the car started to work fine again, for about 4 days only. I drove to the store and when I came back out to start it back up it wouldn’t stay on unless I gave it gas.
I had to drive it home giving it gas and using my other foot on the brake so that it didn’t due out. I checked the job they did and doesn’t even look like they did what they said they did. I looked at the botched shrink tube job they did and it just doesn’t look that professionally done. I did call the guy and he gave me an excuse and said that they short must have traveled further and he was surprised that the car was even running when they were done. I of course just hung up the phone after hearing that. I did a little looking around the engine and I noticed that if you unplug a vacuum tube and press on the gas and hold it at 2000 rpm for a few seconds and let off the car will stay on, but the moment I plug that hose back up with my finger or plug it back in the tube slot, the car idles rough for a few moments and dies.
Firebird - Pontiac :: 1992 Often Stalls When Coming To A Stop
Wife's daily driver often stalls when coming to a stop. I changed MAP, TPS, Fuel filter; Reputable mechanic changed IAC, Plugs, Wires, Cleaned Throttle Body. We reset computer and relearned idle several times, ok for a while then starts stalling routinely again. What to do next? Owner, driver, wife is getting frustrated with the big money spent to no avail to date and I am worried it will stall at a dangerous time, when she is driving. She loves the car - has had it for 20 years and wants to keep it. I need it to be safe and reliable for her.

Firebird - Pontiac :: 1997 Becoming Hard To Start
My 1997 Pontiac Firebird Transam Ram-Air with 169K miles is becoming hard to start. It used to start right up with the first key-switch. Now, if the gas level in the tank is below 75% it will not start on the key-switch. However, it would now normally start right up on the second key-switch. However, very recently the car is now needing the third key-switch to start with lower gas levels in the tank. I MAY be noticing a difference in starting reliability with change in temperature. Lower temperatures seem to increase the frequency of starting on the first or second key-switch. Higher temperatures seem to require the third key-switch to start.
This slow to start behavior manifests its self after the car has rested for about an hour or longer. A friend checked a fuel check-valve immediately behind the engine when the. However, he found fuel there. The local GM dealership claimed they could not find the problem and suggested a new car battery and then a tune-up for $1K. I suspect the problem is a fuel pump in the fuel-tank or associated seal degrading. What is the actual cause of the observed behavior?
Firebird - Pontiac :: 1998 V8 Will Not Crank Or Start
I have a 1989 formula firebird 305 v8 automatic that I am having an issue with. I drove to the next town over, on my way back it stalled 7 times, started back up everytime. On the 8th time it completely died. I have power to my lights and everything still just no cranking and starting. Most the time it was stalling was when i started to slow down for a stop it would shut off. Got it pushed home. Had my battery and starter checked, battery was bad, and starter solenoid was bad. changed both and still nothing. The security light dont come on (just when you first turn the key like usual it turns on, but right back off) I have not a clue where to go from here.

I just bought a used 95 pontiac trans am. It has 121,000 miles on it, 6-speed manual, 5.7L engine, all stock. Well i bought it with oil leaks and they turned out to be worse than i thought so i had to reseal pretty much the whole front of the engine from the o-ring seal to the camshaft seal, etc. That took care of the oil leaks. Well then it started to overheat so i replaced the water pump. Problems solved. Then a spark plug came loose. No prob. Well 24 hours after getting it out of the shop from the resealing i break down.
Now they say i need a new wire harness. No prob. So now I've put $2,000 into the car (that's including new tires). SO ONCE AGAIN WITHIN 24 HOURS OF LEAVING THE SHOP i break down again. So I take it to a different shop again to get a diagnostic. They won't be able to tell me anything until monday but they put on a new air intake boot (without my permission because mine was taped to secure it better and i knew it wasn't leaking air) and it cut off on them again in the shop (so I'm not paying for the boot). When i break down it happens unexpectedly just like I've run out of gas. Well once there was almost like a split second of a lurch but other than that its always been a smooth break down. No bad sounds or anything. And the motor sounds great and the car runs really well until it just stops... Then if i let it sit for a little while it will start back up and go for a little then stop again. No one can really tell me whats wrong with it.
My fuel pump seems to be fine. alternator seems fine (my lights don't dim or anything). Distributor maybe? Or could it be the fuel filter? And isn't there something i can do about the shop? Wouldn't a prudent shop at least run the computer on the car? I don't think they did because at the shop where it is now they said that 6 codes popped up on it. So they want to erase them all and run the car and see which ones come back up. So can't i take the other shop to court for neglect in their work? I mean breaking down TWICE WITHIN 24 hours of leaving them. And then the rest of the afternoon they wouldn't even pick up the phone...

My car is a 1985 Pontiac Firebird
So I was drive around 45mph when I noticed that the accelerator stopped responding, it didn't make any obvious noises. I hadn't run out of gas and the engine was still running. I started pulling over to the side of the road and noticed that the power steering and the power brakes were no longer working. I got it to the side of the road and shut the engine off, I waited a minute and tried to start it again, the engine turned over but wouldn't start. I tried this a few more times with the same result.
I can't afford to take it to a mechanic so I need to figure out what's wrong and try to fix it myself. The car has a slow oil leak. As recently as a few months ago I replaced the battery and had to replace the alternator, since then it has been running fine. I checked the belts and all of them are still there, a friend of mine told me to wiggle the pulleys and make sure they were all tight, I did so and found nothing wrong with them and none of the belts are loose. What could cause all of these things to go wrong at once?
Firebird - Pontiac - Noises :: Ringing Appear From Front Of 1996 V6 Engine
My 1996 Firebird with 3800 series II V6 engine makes a ringing noise. The noise appears to come from the front of the engine (pulley area) and sounds like an old fashioned fire alarm. It usually occurs after the engine has warmed up and cannot be heard from inside while cruising.
View 4 RepliesGasoline - Firebird - Pontiac :: 1985 - Intermittent Lack Of Power
I have an 85 Firebird V6, 2.8L, tuned port injection, we bought it new and I have changed the oil every 2000 miles, it still runs great, except… The fuel pump gave out, I replaced it with a new Bosch, in the process I tried to replace the fuel filter, the line was rusted, it broke. I had to replace about 2 ft. of metal line with nylon tube, I also had to install a fuel filter with quick disconnect fittings, the filter is not the original but some generic because the original metal threaded fittings are gone. It runs great up to about ½ throttle, if I try to accelerate more than that it loses power and almost dies. If I turn off the ignition and restart the engine it runs fine for a while, full power all the way to full throttle.
I’ve noticed that if I keep the fuel tank full the problem happens less often.My theory is that the fuel pump is aerating because of not enough restriction in the fuel filter because it isn’t designed for that car, if I keep the tank full it is harder to start the aeration and stopping the pump and restarting it stops the aeration for a while. If I could get a fuel pressure gauge and be able to see it while I’m driving that would be great, but how? Also, what does the fuel pressure regulator really do? Does the fuel pump run all the time the engine is running? It also sounded like an electrical problem but it idles well and it is very smooth up to about ½ throttle. Could I just have a bad pressure regulator or does my theory sound like it makes sense?
Firebird - Pontiac - Chevrolet - Camaro :: 1991 - Overheat Occasionally?
I recently bought a 1991 Pontiac Firebird Formula 5.7L TPI with 124k. We was driving it home when noticed it was getting really hot (240-250). We pulled over at a gas station and gased it and let it cool off. We had been driving in the city at about 4 o clock for about 7 miles if that makes a difference. When it cooled we tried again. We got about another mile and the temperature would stay down so we pulled back over. We inspected it. The oil pressure showed really zero but we checked the dipstick and it looked okay. The engine sounded normal and the radiator is fairly new. The fan was blowing. We noticed that after it cooled off if you hit the gas the oil pressure would go up (similar to a tachometer...i thought that was weird). After if got cooled and we got on the open highway the temperature stayed normal and the car performed like it should. We think its the thermostat but are not sure.

My 1994 TransAm has 70k miles. As I';m driving, I'll notice the tach needle drop to zero with no warning, and the car just dies. Battery is fine, gas tank is full, and it soon starts again and works normally. Friends have suggested the timing belt (or chain?) may be the issue, and one day, it won't start again, or it will break and ruin the engine. She, like me, is an antique -- is it time to take her in to the repair shop, and if so, is it costly?

I have a 92 grand prix. Out of nowhere when I hit my brakes the car would sputter & eventually die. So I had my break booster replaced & now not only does it still sputter it's has a lack of power when accelerating & I can smell a little oil burning. It hasn't stalled but it sure isn't running smooth. Is the booster bad? Do I just need a new air filter. I've haven't seen any leaks & the brakes work fine so I don't think it's the master cylinder.
View 1 RepliesTrans Sport :: 1992 Pontiac - Cylinder 6 Not Firing When Engine Hot
We have a 1992 Pontiac Trans Sport with the Chevy 3.1 V6 TBI engine.
Engine was running poor because of a faulty Coolant Temperature sensor (rusted-out pins). Changed the sensor and cleaned-out rust from the socket and now it runs smooth when cold with decent acceleration.
Problem is that cylinder #6 is not firing when engine is hot at operating temperature. Engine shakes lightly but performance remains good.
Distributor, rotor, spark plugs, spark plug wires and Oxygen Sensor were all changed 1 week ago with new ACDelco parts. What to check next?
Trans Sport :: 1992 Pontiac - Huge Vacuum Leak And MPG Loss
One of the '92 Pontiac Trans Sports (3.1L V6 engine) had developed a huge thirst - the fuel consumption had doubled along with a serious loss of power. All ignition components - distributor cap, rotor, spark plug wires and oxygen sensor are new ACDelco's.
ECM is not throwing-up any fault codes but we suspect a vacuum leak since this engine runs better with the air intake covered-up almost completely.
Is there any way to trace and fix this kind of issue? Any vacuum diagram for this car - I couldn't seem to find it in the GM Service Manual... How would you suggest we proceed?
Trans Sport :: 1992 Pontiac 3.1L V6 TBI Engine Refused To Start / Fuel Pump Relay Error Code
We have a '92 Pontiac Trans Sport with a 3.1L V6 TBI engine. Last Sunday evening it refused to start like someone left the transmission in Drive and the Park/Neutral switch was preventing it to start. There's the buzz sound from the fuel pump when you put the key on then nothing when you turn it to start the engine.
I checked the Park/Neutral swith by connecting an ALDL cable to the OBD port and it indicates correctly when I move the lever to Drive or Parking/Neutral. The only error code stored is "Fuel Pump Relay" but the Fuel Pump appear to be working?!
Battery is good, fuel pump fuse intact and the Park/Neutral switch appear to be working. How we can tackle this problem?
Celica :: 1992 2.2 - Idle Surge Between 500 To 750 Rpm
My 1992 Toyota, Celica had developed a really weird idle surge. The idle surges between 500 to 750 rpm. The surge goes away with the AC on and it idles steady at 900 Rpm. It also has a slight off idle bog that may just be another symptom of the weird idle.
I did the diagnostic test today and it doesn't flash any codes. I pulled the EGR valve off and cleaned the gunk out of it and it didn't make any difference. I tried to check the timing and it idles so bad the timing bounces 7-10 degrees with the surge. When I did the jumper to check the timing it would kill the engine. The plugs and wires are new with in a couple thousand miles. It runs fine above idle and pulls to redline easily in the lower gears.
Yesterday when I was messing with it I had the car running with the air boot from the air cleaner to throttle body off. I sprayed carb cleaner into throttle body and it seems to clear up a little bit. Then it went back to surging again.
I tried to pull the TPS off yesterday and of course the bottom screw stripped out. Now I will have to pull the throttle body off to get the screw out. I wish it would throw a code so I could have it give me a clue.
Celica :: 1992 - Car Ticks At Idle
I just bought this little car. It ticks at an idle and it burns 1/4 qt of oil a month. It doesn't stop ticking when I add oil so Im at a loss.. It isn't a loud tick either. It has 200,000 miles on it but it is in great condition besides this.
