Recently my service engine light came on. I took it and got it check and was told it was to O2 sensor. Once I got the replacement I tried taking the old one off but can not get it lose. I have used WD-40 to try and get it lose and it won't move. I was wondering if anyone had replaced thier's or has any ideas how to get it lose.

had my dealer do it under warranty, maybe get one of those haynes books

Try to tighten before you losen, that usually helps, this why you won't break it off. When I say tighten, I mean just get it to budge in the tighten position, then back it off.

Also, you can use something called "Knock 'Er Loose." I helped me get the exhaust off of my 89 rx-7 ( the car came from the Northern States).

would take it to the dealer but the warrent and the extend warrenty has long expired. I will try these weak end the tight to loosen method, and I guess if that doesnt work I will try the knock er loose. If not guess I will have to take it in and have it fixed. $107 an hour labor here.

Damn that is some serious rape!!

I get ticked when I pay 50/hour!
