Question: Engine Stalls When Hot?

What causes RPM to fluctuate while idling?

What causes engine to shut off while idling?

Faulty Oxygen or Mass Airflow Sensor



Two of these sensors play a significant role in why a car engine stops while idling. Then your engine might not receive enough air, which it needs to power itself. When there’s a lack of air, it leads to a lack of power, which can cause your car to stall while idling.
