Car Stalls When Stopped

If your engine dies every time you stop at a light or in a drive-through, the idle system needs attention.

A car that stalls when stopped shares many causes with idle stalling — the engine can't maintain enough RPM to keep running without throttle input. A contaminated idle air control valve, vacuum leak, or dirty throttle body are the usual suspects. The engine may also stall when you shift into drive or reverse because the added load from the transmission pushes the already-low idle below what the engine can sustain.

Another common cause is a failing torque converter lockup solenoid that doesn't release when you slow down, essentially keeping the transmission locked to the engine and stalling it like a manual car with the clutch engaged. Carbon buildup on intake valves — especially on direct injection engines — can also reduce airflow enough to cause stalling at stops. Scanning for codes and monitoring idle RPM data usually points to the issue.
