boy, you were right. The O2 sensor itself is very easy to replace, it's connecting it up to the wiring harness that's the tough part. I crawled underneath my Jeep to do this job and found that there was no way I could reach up above the transmission to access the plug. It does look like it's accessible from above if I were to remove the center console, and the shifter bezel. Do you know how to do this?
