What causes fuel soaked spark plugs?
A wet spark plug likely means that it hasn’t been firing due to engine flooding or a bad ignition cable. Dirt or moisture on the outside of the spark plug that provides a conductive path to ground, or an internal crack in the spark plug’s ceramic insulator that shorts the plug to ground also can be the culprit.
How do you stop spark plugs fouling?
The spark plug firing end temperature must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. This is called “thermal performance,” and is determined by the heat range selected.
How will you identify if the spark plug are in good condition?
An engine’s condition can be judged by the appearance of the spark plug’s firing end. If the firing end of a spark plug is brown or light gray, the condition can be judged to be good and the spark plug is functioning optimally.

Where are the spark plugs in a Toyota?
Spark plugs are a serviceable, yet extremely important, part of your Toyota’s engine. They sit inside the cylinder head where they create the spark that ignites fuel — the combustion that enables your engine to run. Spark plugs that have outlived their time will cause misfires in your engine — robbing it of efficiency and performance.
