I get a lower than expected idle (500), that drops even lower when the a/c clicks on. Occasionally after restarting the engine when its already warm, I get a rough idle until I punch the gas a bit. Then its fine....

Thanks!
First, clean the throttle bore..this takes care of most low idle complaints on these vehicles.
There is a GM Technical bulletin addressing your concern..I'll post it tommorow when I get to the shop.
DO NOT adjust anything till you read the bulletin
