i have a 1994 pontiac grand prix that has had problem after problem cinsce i bought it in 2003. it had like 67.000 miles and within a week i had to take it to the dealer to install a 400.00 EGR valve. now with 114,000 miles the problem are still coming. during last year i noticed a strong odor of gas then to realizes that gas was puring out the filler neck when i pumped it in. i ignored it because it was a small leak. i had to take it in for inspection to find that from the gas tank back was rotted out. a little thing the dealer neglected to tell me. never the less i pulled some strings to get it to pass. i knew the guy and i plan on trying to fix it. but with more problems it decided to not start. i turn the key, light stay strong and nothing. no click roar or anything. this car has that chip on the key could that be it. please can anyone help.

My Grand Prix gave me a shock the other day. I came outside and it started turning itself on and off, and it would stay on for at most 5 seconds. Of course no one was in the car and there was no key in the igniton and it doesnt have a remote start. But it was starting itself. Now have I either bought myself a Transformer or is there some major electrical problems going on somewhere that i dont know how to find. Any suggestionsfor where the problem is occurign from?

Hi I wonder if anyone can help?
I imported a 1998 Pontiac Grand Prix to the UK as the begining of the year, had no problems until recently.
The car starts, however as soon as it is running it starts too stall and sucks in load of air, blows back through the exhaust and dies, very odd, fuel is fine!!
Anyone have any ideas?

I have a 2001 Pontiac Grand Prix and it has insane problems. The Service Engine Soon light came on a few days ago and has yet to turn off. Also I get the Tac dropping to 0 and then about 5-10 seconds later the Traction Control turns off. Also when the car is cold it seems and if I am going around corners or up a hill the car will stall and sometimes it will start right away and other times it takes 5-10 minutes for the car to start. Any ideas? The car has regular oil changes and when I bought the car (summer 2004) I had the thermostat fixed and later on (mid 2005) the servies engine soon light was on forever and it turned out I needed a new Catalytic Converter and a tune up.

I have been having stalling issues with my car 136, 000 miles.The car would not start, if you waited sometimes it would. Then it started stalling while driving, took it to the mechanic had bought a new battery, did a tuneup. Installed new plugs, wires, fuel filter, bought a new battery, reset the computer, then the stalling started happening on the highway!!!
I used to be able to put in nuetral & it would restart and I would put into drive and keep going. It wouldn't happen for weeks then it would get worse, then stop and start again. Now when it stalls it won't start for a good 20 minutes, too dangerous to drive, My mechanic has had it 5 times over the past 6 weeks. He said there's nothing wrong with it.My husband thinks it might be the crank shaft sensor.
I also have problems with the heater only working on 5. I did find the threads regarding the blower motor assembly & the ignition wires. Any feedback on the stalling issues would be greatly appreciated!!! ">

I have a 2004 Grand Prix and I'm having similar problems. How much did it cost to fix the thermostat and a new catalytic converter?

Cars stalls but starts right back up. No codes in the system. Replaced the theft control mod.

Wondering if anyone has heard of issues of amber engine light on, reduced power, and traction control light on, before. We have had it to the dealership, and they never find anything wrong with it. It just feels like I have a LEMON!! This is not the first problem we have had and this car is brand new off the lot June 2007. The dealership also did not offer any solution, and just said, it was like finding a needle in a haystack.

Ok here it is answers to alot of questions.
None are cheap.
Stalling and not start up right away, But will after a few minutes?
Oh it will only get worse. It will soon take up to hour before re start!
Dealer even pontiac will fine no issues.
It will subside in cold weather to a point.
Answer.......... Crank Shaft Position Sensor Is Getting heat soaked.
And slowly diying.
Heat soak send bad or no info to Modual under coils Thus Over heating it
And it goes out as well. Random misfire. Lean bank 1 Will show
just b4 it all dies. When it does die for last time is sends mass of High voltage
spark form coils Back thru system to ECU and Camshaft position sensor.
SHIT SHIT SHIT.
Well pontiac Admit to this NO!!
Where did I get INFO Had Car On dyno 3/4 throtle for 2 hr 45 min with Sun Diagnostic Hooked to all the above Parts, and more when it all gave loose.
No I did not hut motor. New Checker auto parts a Cool 1K and all is good
Oh dynoed it again to See CSPS at 140 degrees and climming to 273
after 1 hour. Where the hell is is getting it from.
Serp belt is getting hot from who knows where?
FIX? Replace CSPS ASAP with what? Dealer delco part.
Make sure the lower chin on bumper and air flow to lower engine is good
I could see some one getting some duct work down there.
Then Sell the hoe!! lol
