[Jbauer]

so that light your complaining about won't come on..

Did you just install an o/r pipe? If so, you need MIL's or a tune.

 

[Jbauer]

I've always wondered about the tuner.. If i disable the rear o2 sensors with a Tuner, does that mean i will not have ANY codes related to the REAR o2 sensor? None what so ever, no matter what i do, the computer will just not acknowledge it?

any one here have a pix with mil install ? so I still leave those 2 rear 02 plug in the exhault but leave it unplug and let it hang ? or tie it up to something , so it wont fall to the ground ? and then plug 2 o2 mil into the plug that go to the computer ? thanks

 

[Jbauer]

what you do mmmmk, is that you just buy the damn mill, mmmk? And then, If you've ever solved a simple puzzle, or plugged in a 2 way electrical extension to Vaccum your car, an unbelievable sense of common sense will come upon you, MmmK?

I think it was more of a reference to Mr. Mackey from South Park as opposed to him ripping on your English. Mmmmcay now?

the only thing the rear o2's do is make sure the cats are there/working
