What does engine cylinder misfire mean?

[MacRonan]

Engine cylinder misfire refers to a single cylinder not working. The causes and solutions for misfire are: 1. Incorrect ignition timing, abnormal spark plug gap, carbon buildup, high-voltage wire leakage, open or short circuit in ignition coil, faults in ignition module and circuits, requiring replacement of spark plugs or ignition coils; 2. Fuel pressure too low or too high, open or short circuit in fuel injector coil, mechanical sticking, etc., requiring adjustment of fuel pressure or replacement of fuel injectors; 3. Clogged air filter, air intake system leakage, other faults in engine electronic control system, requiring replacement of filter element; 4. Faults in valve train, poor sealing between piston, piston rings and cylinder wall, damaged cylinder gasket, requiring replacement of related components.
