Running Rich
gotaford 2000 ranger running rich on left bank got a black tailpipe and code default for left bank running rich .I can cut the check engine light by disconnecting battery and drive all day with light out and as soon as I turn it off.. then restart the light comes back on. could it be the o2 sensor giving the computer false read or maybe the MAS ? any ideas or thoughts?
