Hey guys
I went for an emission test the other day and the Hydro Carbons where to high.

I'm trying to replace my o2 sensor on the down pipe, but I can't seem to get it off.

I've tried using vice grips and a adjustable wrench, but it won't even budge.

I'd hate to have to take it to a shop to get it off...

Can anyone help?

Thanks

its in there....thats for sure. if you have an autozone or orileys or advanced....that loans out tools, there is a special o2 sensor socket you can rent. makes a world of difference

Don't fuck up the bung threads like I did though. I he-maned my last one out and completely fucked it up.

Try driving around and get the sensor/header nice and hot then try to get it off. the heat may allow you to get it out easier. the crowfoot style socket for o2 sensors works good....its worth buying you will use it again. I am not an advocate of the socket because there are a lot of situations that it wont fit in tight spots.

Ok, I'll try that tomorrow...tonight I tried working on the speed sensor..tomorrow I'll try the 02

It's the rust.

Soak that bia in some PB Blaster and let it sit for 10 minutes, then you should be able to get it with just a regular open end.
