idle speed control valve dealy majigger yea lots of people have problems with it, its on the back left of the throttle body, about a half dollor sized diameter and 3 inch long solonoid dealy with a single white plug on the end, i found otu thats what was wrong with mine by reving it to the point where it skipped and smackin it with the back of a screw driver pretty hard and it got un stuck inside but only until it went back to idle. if that is the problem i heard taking if off and spraying it down thoroughly with carb or brake cleaner works real good
