Abstract
Methods and systems are provided for controlling spark plug fouling in newly manufactured vehicles. In one example, a method may include operating an engine with a first direct injection fueling strategy including single intake direct injection on an engine start when in a pre-delivery state, and transitioning to a second different direct injection fueling strategy including split direct injection on the engine start when in a post-delivery state. In this way, spark plug fouling may be avoided in newly manufactured vehicles.
