Abstract
Methods and systems are provided for addressing spark plug soot fouling. In one example, spark plug tip temperatures are raised and maintained elevated by advancing spark timing and increasing engine speed, while reducing an amount of EGR being delivered to the engine. The spark plug fouling mitigating actions are adjusted based on whether the engine is in a green condition at an assembly plant or not.
