Abstract
Methods and systems are provided for detecting spark plug fouling and cleaning up fouled spark plug during pre-delivery phase of a vehicle. In one example, a method may include updating a spark plug fouling index saved in the non-volatile memory of the vehicle based on engine operating parameters, and indicating spark plug fouling based on the updated index. The method may further include cleaning the fouled spark plug by driving the vehicle along a planned route.
