Misfiring and O2 maxed out
Pulled all fuses on RCM, all were ok.
Found a procedure for a Mercedes ECU reset, not sure if it had anything to do with?
It's running but O2 problem, if I drive lite all is well, as soon as I hit it O2 goes crazy and it starts misfiring, when acting up it almost sounds like there is an exhaust leak, loose O2 sensor?
