Do both the colling fans work? Has the a/c been serviced recently?

Is the belt slipping? The fact that the car jumps a little when turning indicates to me that either your idle is to low, your belt is slipping so it's not turning everything properly, or the idle adjustment sensor is screwy... I'd start with belts and an A/C service

Don't go & change compressor & clutch just yet... Not until AC pressure measurements really indicate a problem there.

Your IACV is supposed to compensate for the load of the AC. Problems could include dirty/sticky IACV, or your base idle not set correctly. Maybe even a dirty throttle body.

I think the idle control system mayget confused if the AC has more drag than normal. That may indicate a compressor going bad, but leave that for later. AFTER you rule out all the easier stuff.
