Systems and methods for operating a vehicle that includes an engine and an electric machine are described. In one example, operation of the engine may be adjusted to compensate for conditions when carbon deposits may build on one or more engine spark plugs. The engine adjustments may help to remove carbon deposits from the engine's spark plugs.
