#706 of 980 Re: 1992 – Grand Prix Pontiac Cutting Out , Stalling, and Dying Problem [ken7308]
Apr 18, 2006 (7:29 pm)
I had the same exact problems with my 95 GTP. Stalling, no starts, poor idle, cutting out right in the middle of traffic. I replaced O2 sensor, idle control valve, change spark plug wires, you name it. NO results, except less money in my bank. Finally, I figured out the problem. I removed the EGR valve assembly on the top and scraped the inside with a screwdriver to remove the carbon. Put it back on and the car ran like a bat of hell again. I take it off and clean it on a regular basis now. It is much cheaper than replacing it, which is about $150. Also, just a little something else. The EGR valve will not set off any dummy lights and even a scan using a computer won't help. Hope this helps.
#707 of 980 rough idle/stutter
Apr 19, 2006 (9:26 am)
Hey guys im new to the board hope im doing this right. I've got a 95 grand prix 3.1 and i've got a stutter that i dont understand. Sometimes it idles rough, but not all the time only when in gear tho if i put it in neutral it idles pretty well. Secondly when im driving and the car is in over drive with low RPM's it starts to stutter and jerk (like a miss fire) but if i get on it and it shifts down it runs fine at higher rpms (sometimes it feels like something slips tho) i've changed plugs and wires and that didnt fix it (possibly cracked a plug not sure) i've got another coil pack was thinkin of putting on it i've been told a transmission solenoid but im totally confused any ideas? thx for the help my email is (aasjuicehotmail.com) if you it makes it easier to respond. thanks guys i described it as best i could.

I am definately interested in participating in a class action. I HAD a '99 Grand Prix GT that just spontaneously cumbusted on Monday, 4/17. I had just parked the car, after a minute i noticed a little smoke coming from the right side of the hood, then decided to take a look, I opened the hood and saw flames and slammed it shut and called 911. By the time they arrived the whole engine compartment was engulfed in flames. It is a total loss. The fireman said it was too burned out to determine an exact cause. All he could tell is that it started on the right side. Has anyone determined what the cause might be?

My insurance engineer investigator determined origin of fire enough that they (Farmers) are going after GM, but only for the settlement amount they paid me. He told my husband something about the poor design of the engine, that you would never lay a muffler over the supercharger/carbeurator, something like that. He said it was a fire waiting to happen. My scenario is nearly identical to yours, only it happened at night in our garage and could have burned our whole house down!
You can look up my account under the name layne in this forum Dec. 21, 2005. Good luck, I hope we can organize this.

Mine was only a GT though with no Supercharger. Was there anything besides the Supercharger location that they thought could cause it? If anyone has an attorney that is interested in contacting people with burnt Grand Prixs please feel free to email me. Just click my profile to get my email.
#711 of 980 about coolant leakage
Apr 20, 2006 (8:55 am)
My car is 2002 pontiac grand prix 3.1L
I was on the high way the other day, the temperature suddenly went to the maximum and the gas stopped working. I had to slow down to like 40m/h and after a while the temperature just came down suddenly as it went up before, and the gas started to work again immediately. I went to the garage and one of them told me i have problem with the intake gasket and the other told me i need another head gasket. I am really comfused, I think may be the best way is to carry a lot of coolant with me.
Please give me proper advice I really appreciate that.
#712 of 980 99' Grand Prix Dual Climate Control
Apr 20, 2006 (12:25 pm)
First, only got heat from passenger side vents while driver side control worked fine. Just prior to this, there was a sort of flapping noise.
After about a month, the driver side temp. control also went out and now both sides produce nothing but hot air.
When the fan is on I hear a whining screech from the vents. If I quickly turn the fan off then on a few times the screeching noise will sometimes go away, but not always.
What is the problem and how can it be fixed?

I had a 95 grand am that did the same thing. It turned out to be a bad crank sensor. If that isnt your problem I would test your fuel injectors, one of them may be faulty. Hope this helps
#714 of 980 03 Grand Prix GTP High Pitched Whine
Apr 21, 2006 (3:34 am)
I have an 03 GTP that all of a sudden produces a very high pitched whine when I press on the accelerator. Almost sounds like a vaccum cleaner noise. I checked belts and everything looks OK. Any ideas?
#715 of 980 Re: 99 Grand Prix GT power windows not working [aspgp302]
Apr 21, 2006 (10:54 am)
All 4 of my windows have played the "sometimes i work, sometimes i dont" game until they all actually died within the last year. It was the window regulator. which is a pricey part. I have contacted GM and they have reimbursed me for 2 of the regulators. good luck with yours.
