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.

Method and system for plug fouling monitoring and cleaning

An ignition coil assembly having a coil spring ( ) made of electrically conductive material, an electrical coil connected to deliver electrical energy from the ignition coil assembly through the coil spring and a ferromagnetic member ( ) disposed within the coil spring. A resistive spark plug ( ) is electrically coupled to the coil spring ( ). The spark plug and ferromagnetic member ( ) form a high pass filter ( ) and low pass filter ( ) respectively to reduce radio frequency interference.
