Stang hesitates/buckles with a/c on

Mine does this too (it is a stick shift 2000 GT). Also does it on defrost which uses the AC to dry the defrost air. Some posters have told me to replace the idle air control but I suspect it is actually a vacuum leak allowing unmetered air into the intake. I have not found anybody yet who has actally had this problem and fixed it. Car idles fine otherwise so I just ignore the AC and put the convertible top down.
