What causes an engine to misfire at the spark plug?

An engine is considered to misfire when there is not enough electrical energy going to the spark plug to keep it arcing or there is a path- way in the engine for the energy to take that bypasses the plug’s electrodes. Electricity is lazy. It will always take the path of least resistance.

Is the spark plug part of the ignition system?

Something else is going on, and there is a very strong possibility it is with the ignition. The ignition system is considered to be passive.
