If you were driving just fine but your car suddenly dies as you reach a full stop, it could be caused by a faulty idle air control (IAC). The IAC is responsible for controlling your engine’s idling rotational speed. Over time, dirt may build up inside the IAC and jamming it closed, stalling your car while idling.
What can cause a car to shut off while idling?
