The more research I have done, the more people I find that the SAME situation has happened to. I have found 6 other 1999 Grand Prix's where the same thing has happened...turn the ignition off....15 minutes later the car is engulfed in fire. I have also found others with newer Grand Prix's that this has happened to. I am gathering as much information as I can. Apparently this has been happening since 2001, and I even found an investigation of an "engine fire" at www.nhtsa.dot.gov, but it appears to have been closed on 3/9/2004 with no recall. If anyone else has had this happen, or has information, please post. This SAME situation has happened to too many people for it to be "coincidence". Hopefully by bringing the problem to the attention of Pontiac and the goverment, the problem can be solved before one of the fires causes someone to get hurt. Thanks for posting.

The HUD in my 99 GTP started to fade in and out several months ago, and now has completely disappeared. Has anyone suggested a cause or solution to you?

I had the same problem going back for the last few months. The engine would surge a little, it felt like it was driving very heavy, and had very poor acceleration. I had the fuel system cleaned and replaced the fuel filter and that didn't help. I finally gave in and took it to the dealer and they found the catalytic converter was totally shot. They replaced it and it runs great now. The best part was that it was under warranty!

I am having the same problem with my 2000 grand prix gt. On a cold start, below zero, both of my cooling fans were on high and the service engine light comes on. My engine temp does not get above 170. If anyone knows how to fix this I would appreciate the help. Thanks

Start by having any stored diagnostic trouble codes retrieved.

I have a 97 grand prix gtp with only 33,000 miles and the low coolant light is coming on also. The coolant level is fine, but the car sometimes is steaming when I shut it off (its cold here). It also looks like it might be leaking, but not sure if it is a leak or over spill from refilling the coolant and it really doesn't need it. I heard that there is a sensor in the radiator that might not be working and it is sending a message to the engine that there is low coolant. Any ideas on this problem. I really need to find out what the problem is. Thanks.

I hope you've gotten an answer to this question but if not here it is. I had this problem with my 99 GTP recently for about 6-7 months. It got progeressively worse where as once my tac dropped my car would stall out, didn't matter if I was driving it or at a dead stop. I had the ignition replaced, my alarm system taken out (thought it might be stopping the fuel) fuel pump and line replaced. Finally I took it into a pontiac dealership and the said it was a fuel sensor. It's a pretty common problem if your mechanic works on gtp's and will run you about 300 dollars with labor.
