Using TorquePRO I captured a few images :One thing in common between them is the O2 Bank 2 upstream sensor doesn't change under any throttle setting.
Secondly I noticed there is typically a 3% difference in the downstream O2 readings, so question 1. Having an upstream sensor "flat-lining" (not reading) I would imagine means it's dead, and secondly, if it is dead could that be contributing to the 3% diffential I'm seeing and could it also lead to my drop in mileage?
Kinda makes sense right?
And the AFR reads real well, mostly hovers right at 14.7, thoughts?
