Did you let the PB Blaster set overnight? On things that are really stuck, PB Blaster may take a few doses to work it's way into all the nooks and crannies.

Just my .02 and yeah, O2's can be tight!! :beek:

I had to change those on my Mark VIII after I bought it used. They hadn't been changed in ages. I'd start on it, get frustrated, and quit for the day. I didn't get them loose till two days after I started tugging on them.

Just keep at it. Drive it for a while to get things hot, then cool it off with a spray of PB Blaster. Let it soak few minutes, then get to work on it again. You'll do it.

Remember to put anti-seize compound on your new sensors' threads.

Oh yeah; try not to put them on too tight. ;)
