clogged IAC valve (idle air valve on the throttle body with coolant lines going to it) will cause stalling too

first step is to always fix check engine light. If it is on there is a problem

i just had that exact problem like two days ago i changed the (cam position sen) part#su5583 and it was $51.99 and my car has been fine since if but to put it in you will need to remove you valve cover just enough to get your timming belt cover off and youll see the sensor in side there. its like the only thing with wires and rubber boot going through your timming belt cover. if you need pics just ask and ill show you were everything is
