I think that's the one in the back of the engine. It's on the exhaust manifold, where the pipe flange bolts up. You might disconnect that, and then it should be fairly easy. Would have to be done from under the car.

Also, people, why do you (and others) CAPITALIZE every single word? It makes it really hard to read, and is just as annoying as writing in all caps! I used to erase every post like that when I was a mod on a computer related board. Erase and e-mail an explanation to the author. If he did it again, erase and no explanation.

Thanks, oh will try not to write in caps. Hope that makes you feel better.

On my '97 N* I leaned over the top of the engine and used a long extension and a crowfoot O2 sensor socket to get the bank 1 sensor 1 out. It's not fun, and I made sure I bought a AC/DELCO part. I let the engine warm up a couple of minutes, no more or you will fry your hand, to make it easier to loosen. Good luck.
