    It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. It could be a vacuum leak, an idle speed control problem, leaking EGR valve, poor electrical connections, many things is the check engine light on ?

    the check engine light is not on and I replaced the throttle positioning sensor last night and it still stalled on me after that was replaced.
