What are the most common spark plug irregularities?

The following are some of the most common spark plug irregularities. Carbon fouling is characterized by black, soot-like deposits in or around the spark plug’s electrode or insulator. This is often caused by an overly rich air/fuel mixture, long periods of vehicle idle time, and air filter restrictions.

What happens when a spark plug does not fire?

When a spark plug does not fire, as it should, several effects to your vehicle’s performance can become noticeable, and new plugs should be installed.
