...that should never need adjustment. The only time you should mess with this screw is if somebody else has already done so.
Everything on these cars is computer controlled, so if it's idling high there is a problem somewhere. Check the simple stuff like ignition timing, cam timing, vacuum leaks. Check for engine codes (just because there isn't a code showing doesn't mean there isn't one stored). Post back with what you find
