My car has an automatic transmission.

Hello.

Engine stalling can be caused by a wide variety of issues. Faults within the fuel, ignition, or engine management systems can all cause the vehicle to experience stalling. A few common causes of stalling are a bad idle air control valve, bad injectors, a faulty engine management sensor, or even a vacuum leak. As the possibilities are many, I would recommend having the vehicle properly diagnosed to determine your stalling issue and figure out what exactly needs to be fixed.
