Re: Hanging Revs ???
What I would do is take the throttle body off the car and clean the electrical connections to the isc motor and butterfly position monitor (dont know tech name), then take off the isc motor and spray throttle body cleaner into the isc motor and blow it out with air and do the same to the throttle body paying attention to the idle ports (to isc motor) and around the butterfly shaft. Open and close the butterfly a few times while spraying the stuff to loosen it up. Good luck
