Finally figured I'd post up about this.

After my T2 swap was done and all the emissiosn removed (block off plates and the whole 9 yards), I noticed that the clip or harness for the O2 to hook into was gone as well. So I have an 02 in my Racing Beat turbo back that has its clip/harness just hanging out in the engine bay not hooked to anything .... is this supppose to be this way? Or shuold I still have the O2 hooked up somewhow?

Also isa this why I am only getting 140miles/tank on my T2 lol?

Why wouldn't you want one? What good can come from not having one?

i never had an O2 sensor hooked up on my TII ever since i bought the car, it hardly affects mileage but does to a small extent.

if you are getting that poor of gas mileage then you have another reason why it is getting such poor mileage such as boost leaks which cause rich conditions under boost, wrong AFM for the vehicle, dirty injectors sticking semi open or restrictive exhaust(semi or nearly fully plugged cats) which is lowering the VE of the engine.

Well if it was supposed to be disconnected it wouldn't have been there in the first place...

Are you using the original NA harness or a TII one? If it's the original one, where was it before? If it's a TII one, the wire comes out of the harness at the same place as the BAC valve wires.

No. The O2 sensor simply doesn't make that much difference to fuel consumption.
