My wife has a 2006 mercedes c230 sport. It had two codes that were intermittent, they were po012 and po022 it was running fine with no misfires or anything noticable until she came to a stop at a light. It started running rough and almost wouldn't go. Codes now po304 305 and 306. I replaced the cam magnets and got rid of po012 & 022. What could cause all cylinders to missfire on one bank? I switched the cam sensor with the other bank and also the coils, I replaced the plugs, now I am at a loss. Could it be an oxygen sensor. If so up or down stream. Thank Jerry
