What does it it mean if my car turns off while at a stop?

If your car turns off while at a stop, it could indicate several issues, such as a problem with the idle air control valve, a failing fuel pump, or a malfunctioning sensor. It may also be a normal function in vehicles equipped with stop-start technology, which shuts off the engine to conserve fuel when idling. If this occurs frequently, it's advisable to have a mechanic inspect your vehicle to diagnose and address any underlying problems.
