Where is my O2 Sensor located at? The front one. I got it in last week and want to install it today.

Follow your exhaust behind your motor .. its gunna be visible on the top of the pipe before the cat.

Any tips or suggestions on how to get it out? It is really stuck in there, even my vice grips are slipping on it, and I really dont want to strip it or break it off in there. Maybe some wd-40?

yeah i made up a tool to do the job. i don't remember the size but you can get a socket and cut a slot on one side of it for the wire then should go right over top with a 12 long extenstion. that is what i did to change mine
