2006 Mercedes C230 Sport : sudden CEL resulting in rough idle Diagnostic Misfire
Vehicle had been running great minutes before loosing power while in motion, CEL appeared on dash and idle was rough. Plugged diagnostic and cylinder 2 and 5 misfire. With engine running pulled coil electrical plug off and no change to engine idle at both cylinders. Replaced spark plugs,coils, fuel injectors , Mass airflow,Throttle body. Pulled intake manifold inspected vacuum hose swirls,flaps, pump diaphragms. I tested the coil plug for power as well as both injectors.
