Sorry for the potential n%B question.

I bought a TurboXS exhaust and midpipe and am bolting it up. There are two oxygen sensor bungs but one is not reachable. I pluged that one up and am using the other for my aftermarket wideband. This means there is no room for the rear narrowband sensor. I actually had the midpipe and a bung at the shop and was going to have it welded on, but decided aganist it. Why do this if I have no cat?

I know you can drive around without this sensor and that it is mostly for emissions. I also know that unplugging it will through a CEL (which I can disable with ease), but I am wondering what precisely are teh performance consequences of running without this rear sensor. Is there ANY interaction of this sensor with the PCM (perhaps not the fundamental interaction that the front wideband sensor has with the closed loop tables, but any minor interaction would be nice to know.)

I would bet there is a thread around here. If it makes you feel better, please post a link and shout "SEARCH N00B!" Iwill understand.

THanks.

it's there to measure the efficiency of the cat. if you don't have the cat, you don't need it.

I haven't had one for a couple of years...gotta put up with the CEL though unless you have an AP

^well he said he could remove the CEL so he either has the AP or a roll of black electrical tape!
