Yup...sounds like a toasted IAC...you can try cleaning it but I would just get a new one...also check the black rubber "T" fittings around the LIM and under the blower snout...they tend to rot out and cause crazy things to happen

I cleaned my IAC tonight. Need to do the test run tomorrow. It only happens sometimes when the car is warmed up. My IAC didn't have an o-ring. Should it? If its supposed to have one then I am guessing that when its warmed up a vacuum leak occurs around the IAC, hence the fast idle.

Did you every fix the problem? Have anyone else had this problem and how did you fix it.Originally Posted by mikegtp

It ended up being a vacuum leak on the intake manifold vacuum line tee. The one under the supercharger pully. I fixed it and the problem went away.
I fixed another problem too where the car would start up, then stall right away. It was a bad IAC.
