Re: Help me
Ok, its been a while but I beleive it is located on the engine pipe off of the back exhaust manifold and is a pain in the ass to get to, at least that is where it is on my 93, I noticed when I had it on the lift with my 2 foot extension replacing my back sparkplugs!!

Re: Help me
Aww man. I wanted to try and get to it myself. Since you said that it is difficult, I guess that I will have some other person do it for me. One question, do you have to get under the car to get at it or can you do it from under the hood?

You can replace it from under the hood, it isn't that hard. If you look dead center down the back of the fire wall you can see it sitting in the top of the exhaust manifold. You need an extention, elbow/knuckle joint, and a oxygen sensor socket (you can borrow one free from Auto Zone). Unplug it, unscrew it, and put the new one in...Done
