You have a sticking idle air control that will not hold the idle properly under the load of the AC. When you put on the AC it has to open more and it can't react properly due to the "bad" spot.

Reply to Ted G.'s Post: so what is the idle air control, and where is this part on this car
Expert:  Ted G. replied 8 years ago.
It is basically a computer controlled valve that varies the amount of air into the engine at idle. This keeps the idle speed where the computer is programmed to hold it. It is up by the throttle body on the intake manifold.graphic
