Trying to figure out AFR reading
So on my 3rd sensor going into bung it seems to be working. Have idle about 13.5, going down road it's between 12.2-12.8 according to chart that's rich. Pulled #2 plug and it's looking pretty white like it's running lean. Who do I trust, fancy new AFR gauge or reading plugs?
