Soft, black, sooty dry deposits on plug indicate carbon fouling. Carbon fouling is an indication of a rich air-fuel mixture, weak ignition, or improper heat range (too cold). Carbon deposits are conductive and can create a path for spark plug misfire.

What causes white carbon buildup on spark plugs?
Burned. Blisters on the insulator tip, melted electrodes, or white deposits are signs of a burned spark plug that is running too hot. Causes can include the engine overheating, incorrect spark plug heat range, a loose spark plug, incorrect ignition timing or too lean of an air/fuel mixture.
What does carbon buildup on spark plug mean?
Soft, black, sooty dry deposits on plug indicate carbon fouling. What This Means. Carbon fouling is an indication of a rich air-fuel mixture, weak ignition, or improper heat range (too cold). Carbon deposits are conductive and can create a path for spark plug misfire.
What color should a spark plug be?
Normal Condition 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.
What Causes Black Soot On Spark Plugs?
What does black on a spark plug mean?
Carbon fouled Black.
What would cause a spark plug to be black?
Carbon fouled Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.
Can carbon fouled spark plugs be cleaned?
Yes, you can clean an old, fouled plug. However, it's best to replace it with a new plug in most cases. That's because an old spark plug won't give the optimal performance like a new spark plug will.

What causes a carbon fouled spark plug?
Carbon fouling is an indication of a rich air-fuel mixture, weak ignition, or improper heat range (too cold). Carbon deposits are conductive and can create a path for spark plug misfire.
Should a spark plug be black?
Black carbon deposit? Black spark plugs are a sign of a weak spark or too much fuel in the air-fuel mixture.
