1993 Pontiac Grand Prix mileage: 107,750. After starting the car in the morning it idles up to 3000 rpm. It stays up there until the engine is warmed up. I usually have to let it run for a little bit, then shut it off and start it back up which I do numerous times for about 20 or 25 minutes then it finally reaches back down to 1000 rpm and stays there until I let it sit for about 4 or 5 hours. Start it back up after the 4 or 5 hours and it idles right back up to 3000 again and stays until I repeat the above process. This problem is very annoying and frustrating. Any help would be greatly appreciated. Thanks
have the same problem?
