Have you load tested the battery or the alternetor? You may have an issue there. This would affect idle if you are not in gear and under load. Turn on a bunch of accessories, defroster, high beams, heater fan etc. does your idle become erratic and unstable?
When your car is warmed up completely and idling, is the fast-idle adjust screw far away from the throttle stopper or is it close to it?
Check these areas. It is hard to know what your issue is for sure, without being there. My best tool for fixing all of my car issues has been an insane amount of research and reading.
Totally! thanks man ill try these. Yeah like when i roll up the window i noticed the idle changes. and i think headlights.
I just dont know though because with the idle screw closed the car shouldnt run right? mine does... and there arent any leaks. Ill put my ve throttle body on because i found a roller rocker tps for it. And ill clean the IAVC tomorrow
