The term ″engine misfire″ refers to when one or more cylinders of an engine do not create power. There are various probable reasons of engine misfire, ranging from an impure spark plug to blocked fuel injectors and malfunctioning oxygen sensors.
When something in the sequence fails, this is referred to as a misfire.
