I was needing to know how to replace my o2 sensor, where it is, what kind of tools I need, and how difficult it would be to do myself. thanks.

This is what I used. There are cheaper and other ways to do it, but these are kinda the "proper" tools to use. The special socket just has a slit in it to go around the wire harness. I like using breaker bars to get them out because they are super tight from constantly getting heated and cooled.

You definately should do it yourself, it is so easy. Just follow the exhaust manifold back and you should see it.

Wait for someone else to chime in, but I think sensor one is the one in the manifold. There is a second one behind the cat, but I think that is sensor two.

how far are either of them under my car, I only have a pair of ramps , and I don't usually like getting under there unless it's to change my oil and I don't even like doing that.

The primary one is in the engine compartment, on the exhaust manifold. You don't need to go under the car to access the primary one. If you don't have a socket like that, just use a wrench that fits it....7/8" IIRC.

does anyone have a picture of exactly where the o2 sensor is so I know what i'm pulling out, I don't want to end up pulling something else out in the process since this will be my frist time changing it. thanks

its easy to find. you should only need to change the one on the manifold, its the one that affects driveability of the car.

so i guess that's that cylinder bolt thing that's going into the headers right?

Look for the plug looking thing screwed into the header/manifold with the wires coiming out the end.
