Idle hunting issue

Durandal · 06-13-2010, 03:14 AM

I have been having an issue pop up recently now and then but not consistently. Sometimes my idle will surge from 1000 to 2000 as if I have a disconnected MAP sensor. Other times it will idle high at around 1200-1300. When I step on the clutch the idle drops down to 1000 for a second but then back to 1200-1300.Any other time it idles normall at around 1k.

I've checked for boost leaks and just cleaned my IAC valve last summer so I don't think those are the problem. Is the first butterfly closest to the front of the car in the throttle body suppose to be closed all the way? It seems to be open a little bit in the closed position.

*Should mention that I am getting no codes
