What does engine stall mean?

[LilaMarie]

Engine stall refers to an uncontrollable process, whether caused by human factors or not, during the engine's operation. It manifests as the output speed of the torque converter being zero while the engine is running during normal driving, meaning the pump wheel rotates while the turbine remains stationary. Common causes of engine stall include the following: 1. Air leaks in the intake system, such as leaks in hoses and connections, PVC valve leaks, EGR system leaks, leaks at the dipstick socket, or leaks at the oil filter cap. 2. The air filter element is excessively dirty. 3. The air flow meter is not functioning properly. 4. Unstable fuel supply pressure in the fuel injection system. 5. Incorrect ignition timing. 6. Poor performance of the cold start injector and temperature timing switch. 7. ECU malfunction.
