Having problems with your 1999 Pontiac Grand Prix ?
I have a 1998 grand prix and my service engine light came on and then stalled. I was able to start it back up and get home. What could be the problem the service engine light is still on
The best suggestion I can give you is to have the ECM checked for codes. Once you know that it would be much easier to make suggestions for possible correction of the problem or problems. A part store like Autozone should be able to help you check codes.
