There is an "idle up" valve mounted below the throttle body that is designed to overcome the extra load of the A/C. Check it and see if there is anything obviously wrong with it.

No, I didn't say to adjust anything. The is a valve mounted below that to bring the idle up when the A/C comes on and it likely has a problem.
