2004 CL 55 AMG Misfiring
Hello everyone !
this car stared misfiring out of nowhere,cylinder #1 and random misfired , I have replaced--- coil pack, new spark plugs and wires, new crankshaft sensor.
When is starts , its a lot of white smog coming from the exhaust , I can smell unburned gasoline , and some gasoline is dripping from both tail pipes.
It's not loosing any coolant.
Charging system its brand new ,new alternator , new battery, this car has 122k.
I believe it might be the PCM unit.????
Would greatly appreciate your advice .
Thank you

maybe you have an injector that's stuck wide open. An extremely rich condition would explain the bad idle/misfires.
If you're getting mostly P301's I'd start there. Swap the injector with the next closest one on the rail and see if the faults move with it.
