87 sammy, its been idling perfevtly, last night on way home I noticed it was revving at 2k RPM's while in nuetral at a light or with clutch pushed in. Its driving fine, acceleration is fine but all of a sudden its idling at 2k instead of around a smooth 650-700 like usual. ONLY thing that was different about last night was that it was cold out, but it sat all night in garage and its still idling way high even when warm.
