What should I do if my spark plug is misfiring?
I suggest first removing and checking the spark plug and swap in a new one or swap with cylinder next to it. This way the misfire moves to other cylinder then you know it was plug and replace it. If misfire still on number one then check for spark and injector pulse and replace injector or coil as needed. Was this answer helpful?

The statements expressed above are only for informational purposes and should be independently verified.
What are the ignition coils?
Ignition coils are an electronic engine management component that are a part of the vehicle’s ignition system. The ignition coil functions as an induction coil that converts the vehicle’s 12 volts into the several thousand that are required to jump the spark plug gap and ignite the engine’s air-fuel mixture.
