i search on the site and i found something about the IAC ... it could be my problem ??? it is possible that the IAC let pass to much air in the intake at idle so the motor rev up to 3000rpm at idle ????? -
I would go with either the IAC or a vacuum leak. But considering when it occurs, the IAC is a good bet.-Brad-
