I'm gonna be installing a turbo kit soon but my rear O2 sensor is broken. I tried to replace it but it's rusted stuck on the crappy aftermarket exhaust. Of course it's causing a CEL, but can I just leave it as is and hook an A/F ratio gauge up to the front O2 sensor and have it work properly? Or is the rear sensor going to mess up the whole thing? Thanks guys.

the rear sensor to my knowledge will not give an a/f reading because it is only for emissions. the rear wont make anything go wrong with the a/f gauge. the thread below gives instructions on how to get rid of the cell. Good luck.
