Four-in-one ignition coil is on fire

Symptoms of intermittent misfire in the ignition coil include:

1, the short circuit of the ignition coil winding will make the voltage generated by the ignition coil too low, resulting in insufficient ignition energy and rapid blackening of the spark plug electrode;

2. The ignition coil is disconnected or grounded, which does not generate high voltage and cannot ignite;

3. Discharge occurs on the surface of the ignition coil, and discharge flashover occurs on the outer surface of the ignition coil;

4. The mixture of gasoline and air in the cylinder cannot be ignited and will be discharged from the exhaust pipe.
