Quick stock O2 sensor question
It's been forever since I tuned a car with stock O2's in it. The car is idling like **** and one of the O2's swings from 850-750 or so and the other one swings from 850-250. I know that they are supposed to oscillate. I just don't remember how much. Which sensor or bank has the problem?
