This problem is really starting to drive me crazy, whenever I start up my car it idles really ****ed up. The best way I can describe it is the motor revs up then acts like it wants to die but its like the computer revs the motor up again and the process starts over again. When it finally does stabilize out its idles at 1000-1100 RPM! I have traced all the vacuum lines NO LEAKS that I can see or hear.

SOMEONE WHOS HAD THIS PROBLEM PLEASE HELP ME! It seems like Ive brought this up a million times and no one knows what the hell causes it. Most people end up spending a butt load of money on their engine and they dont have any idea what fixed teh problem.

Ive already rebuilt the throttle body, did not help. The EGR vavle costs so damn much that I wont be able to afford to replace it for a while. Im starting to wonder if maybe some kind of vacuum leak is occuring in one of the sensors that get a vacuum line plumbed into them.

The exhuast manifolds leak slightly but I dont think it has any affect.

I just burned the tires damn near off of the car in anger over this STUPID problem.

 

try o2 sensor worked for me
