Miss: The term “miss” is often misunderstood, but refers to a situation when the engine runs on less than the number of cylinders it is equipped with. It can refer to a constant condition or an intermittent one. A constant miss means that one or more cylinders is not firing at all. Intermittant misses will come and, a cylinder might fire most of the time.

Piston Rings: Metal rings around the piston. There are 2 primary types, compression rings and oil control rings. Compression rings help seal the piston to the cylinder to ensure proper compression. Oil control rings scrape excess oil off the cylinder wall to keep it from being burned in combustion.
