So - I installed the infamous narrowband a/f gauge (to the rear o2), and now with that thing flashing in front of me all the time, it makes me worry/begin to think that I'm running too lean... I know it's a mostly useless gauge, but I had an opening in my pod... in hangs out in lean most of the time. However, I have a data logger which communicates over OBD2 (CAN) and the front o2 sensor is displayed on the bus and is reading stoich (14.7) at highway speed and ~11.2 under wot - should I be alright?
why would the narrow band be reading so high? is it shot?
