o2 is being weird
 

ok my pass post cat sensor (since my cats are gone and the fronts are tuned out) is stuck on voltage .455, which is the error for it being bad or not plugged in, so i replaced it, and it still is on voltage .455, wtf???

if the 02.s are all gone i would assume the program or tune is faulty.

well the fronts are tuned out but the backs are still there, my driver side still works but its just the pass that died, can just the pass side wig out on the tune and the driver stay in liine?

i would look for a bad connection or wire first. dang computers, i dont know if the tune could do it but im sure the computer can.

All wires are good, still runs good just bad mileage, I called my tuning guy and he is going to reload the tune on Monday so il let you know then
