Does anyone have a good idea of how to get the upper o2 sensor off easily? I believe my cat is getting plugged up and someone said to take the upper o2 sensor out but I am having a hard time getting a wrench on it... any suggestions would be much appreciated... thanks

7/8" wrench
O2 plug socket and ratchet from parts store.

I think the socket was about $15 when I bought mine 2 years ago... maybe a little more, but the few times used it has more than made up its cost. A wrench is a booger to get it off with considering how little angle room is behind the motor, do-able but busted knuckles will be in your future.

Even with the o2 hot from driving the car, and SOAKED in wd40, I still managed to break a craftsman 1/2" drive extension.
PS don't use 3/8" drive, broke a swivel trying that.
That's my story, good luck.

Shoulda used PB Blaster. It works well for those "rusted" in place parts.

Pssh wd40, pb blaster, same thing.
OP, better yet, just cut the cat out. I did that so I don't have to worry about it getting clogged.

pb blaster is 1000x's better than wd40 but a socket on a 3-6 in. extension works great for o2's. May have to run the motor for a while to heat it up.
