What Causes Engine Misfire to Trigger Fuel Cutoff?

[McBriella]

Reasons for engine misfire triggering fuel cutoff: overheating of the radiator, overheating of the automatic transmission, excessively high engine RPM, etc. Detailed explanations of the reasons are as follows: Overheating of the radiator: Due to prolonged or high-speed operation of the engine, the radiator may overheat, and similarly, the automatic transmission may overheat. These conditions will trigger warning lights and audible alarms. In particularly severe cases, the vehicle's onboard computer will cut off the power supply and stop fuel delivery. If this occurs frequently, it is advisable to check the radiator, transmission fluid, engine oil, etc. Excessively high engine RPM: The tachometer usually marks the engine's dangerous RPM range with a red zone. When the needle enters the red zone, the engine typically stops fuel injection.
