sonyman87 Posted September 1, 2003 Report Share Posted September 1, 2003 OK the problem. I got into my car this morning and Turned the engine over it revs to 3 grand and then dies instantly. Do it agian and it tries to idle at 1000rpm but sounds like only half the engine is fireing. Sounds like a v8 idle at 500rpm. Some white smoke gomes out the exaust (burning oil i think) and then dies in a matter of seconds. I do this for a little bit and give it some gas forcing a 3 grand idle. I Put the car in gear and its fine. No miss, no stutter. nothing the car drives flawlessly. Plugs and wires are new only 2 months old along with new timing and belts. Freeflowing exaust and intake. The car can get ~30+mph on a highway at 72mph. The rest of the day it is completely normal. I have seen this happen maybe 3 times this summer. Its kinda random and rare. i was wondering if it might be one of the coil packs, fuel injectors, or a sensor??? this is a 95 lumina 3.4dohc auto 150,000miles Any ideas? Im going to college in springfeild so i drive 250 miles twice a week. I dont need to be stranded along the highway if something is about to die.

Robby1870 Posted September 1, 2003 Report Share Posted September 1, 2003 Idling to 3 grand sounds like a vacuum leak to me. Thats the first thing that came to mind Robby Quote Link to comment Share on other sites More sharing options...
SmokesGTP Posted September 2, 2003 Report Share Posted September 2, 2003 If it was a Vacuum leak it would probably happen all the time though right? If it's only happening occasionally I would lean toward electrical but someone who knows what their talking about, preferably Erik or Ben about will step in right about now.

sonyman87 Posted September 5, 2003 Author Report Share Posted September 5, 2003 UPDATE the problem seemed to have fixed itself. it dosnt do it anymore. although it does have a relitivly high idal 1.5k after hitting the gas to go after on startup. like the engine is trying to warm up.. after warm engine runs great Quote Link to comment Share on other sites More sharing options...
