Thanks - I think I will just buy a new one. All I need is the one in some rear bank 2 or something. I have been driving with a engine light on for a few months now.
i payed 90+$ for mine!, i even went to autonzone and they said thats the goin price for the coug. so the shop i had em done at, to replace all 4......ready?............................charged me 650$ to replace all 4 o2 sensors
I have good news. Went to autozone and they charged me $67. Went home to change it and found out it was the wrong one. Mine had a circular plug, while the one they gave me had a u-shapped plug. Sprayed some pentrating oil on the front one, and removed. Took about two minutes. Took both of them back to autozone and they brought out the post 1/3/99 (figuring I bought my car in Dec. of 98, I don't know how this happened) and seemed to be the correct one. I have the part numbers at home. They actually had two different ones w/ the same connection, the only difference was the wire length. So I got the longer one, just incase it was my back one that was bad and it was only $49.99. Luckily for me it seems to be running fine today.
However, I did look at the back one and it seems to be accessable from underneath. I took some pics and maybe considering writing a How-to if I get the time. I am not sure if there computer is wrong or not, but I would recommend getting under you car and seeing what type of connector you have first u vs 0.

The uppers have the U-shaped plug. The lowers (downers?) have the O-shaped plug. The lowers come in at least two varieties: green and blue. Early cars use blue. The sensors look alike but the alignment dowels are in different positions.
Well, maybe I did replace a downer (it was on the front lower close to the frame under battery sort of), but I don't have a cel anymore. So I am calling it prob solved for now.
