What makes a car die when coming to a stop?
Unmetered air entering the engine will also lean the air fuel mixture, causing the engine to stall at idle or while coming to a stop. A faulty or worn fuel pump or some other component in the fuel delivery system can cause the engine to stall at stops.
Why would a car stall when idling at a stoplight?
Your vehicle is filled with different sensors. If either of these sensors is relaying incorrect information. 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.

It then restarts the engine automatically when the driver lifts off the brake (or puts in the clutch to select 1st gear) to get going again.
Why do I keep stalling on hills?
