    They can stall at idle with the AC if the throttle is dirty. Intake gasket vacuum leaks are common as well. Usually the idle will be affected more cold if the intake is leaking.

    Has the check engine light been on? If it hasn't it doesn't mean there are no codes but if it has there are probably some stored in history.
