How is your base ignition timing setting? Turning the A/C on causes the ignition ECU to advance the timing a few degrees which increases idle speed when the throttle is closed. Turning off the A/C (at idle) retards the timing and reduces the idle speed. A base timing setting that is too retarded may cause a stall when A/C is turned off.
