Hello, my 2008 CL65 has misfire codes-CEL light on, and the garage changed the right side ignition coil, ignition transformer and spark plugs. They advised all was fine now. Drove the car out and after driving a total of 60 kilometers the CEL light is back on. This happened when I pushed/accelerated the car from 80kmph onwards to 120kmph. Also had random vibrations thereafter. The car sounds a bit different too on idle! What could this be?
