    The throttle position switch could possibly be the cause for stalling but I hate replacing any part with out knowing it will fix the car. Your car has good on board diagnostic capabilities that monitor things like fuel trim, if your car has a vacuum leak long or short term fuel trim data may indicate a leak. air flow meter values can be read from a scan tool to verify the air flow meter is operating correctly or not. Starting with the basic when was the last time the spark plugs were replaced, throttle body cleaned ect...
    The throttle position switch is an integral part of the throttle housing.
