This 2015 Mercedes Benz ML350 had a rough running engine and the problem was intermittent. I pulled two trouble codes from the ECM, which were P0352 and P0302. P0352 refers to a ignition coil problem or its related circuitry on cylinder number two, and P0302 refers to a misfire on cylinder number two. In this video I replace both the coil and spark plug on cylinder number two. Off camera I replaced all the spark plugs on this engine, which is why there is a dramatic light change between clips near the end.
