Just curious, maybe one of the reason's my car doesnt feel all there after the s/c is because the upstream, passenger side 02 sensor is dead. Im getting it replaced tomorrow but still im curious

How would it effect my car not having that 02 sensor?

unless i'm mistaken if the PCM sees a dead o2 sensor it'll go full rich (or a pre-determined amount) as a precaution, in other words it'll stay in open-loop

ah that would explain that, plus the temporary tune i have is very rich to stay safe, but this definately all explains my 12mpg and piggish response
