Need Engine diagnostic help 1999 ML430
Just ready to go on a trip to relatives. What a way to start a holiday..needless to say I won't be taking this on a trip, But hopefully weather holds out mild in NJ and I can work on it next week.
I had been getting a P0141 O2 Bank 1 sensor 2 engine light and purchased a new sensor but never got a chance to put it in.
Today the truck started to run very rough.....Ran a scan and got codes
P0301 ( Cyl 1 misfire )
P0305 ( Cyl 5 misfire)
P0300 ( random Cyl misfires )
P0161 O2 Bank 2 sensor 2
If someone can please help identify a place to start.......plugs/wires...other etc.....I would greatly appreciate it! Thanks in advance.
And could the sensors be contributing to the misfires?
