Trick to loosen O2 sensor?
#2
Get some penetrating stuff on there somehow and let it sit for a while. Spray that **** in the the lid and pour it on the O2 from the top or something.
If it truly won't come off, then unplug both sensors and take the dang Ypipe off the car, then you can torque on it as many ways as you have to.

The 96-97 y-pipe is truly a pretzel and is not very accomodating in getting to all of the 02 sensors. As stated above, you will have to find some way to get some penetrating oil on there, or drop the y-pipe depending which sensor you are having problems with. Sometimes you have to heat them up first to get them out, but seeing that you cannot reach it with penetrating oil, it is probably safe to say you couldn't access it with a heat source either.

I've done that to a Craftsman socket...but I did have it on the crank hub bolt trying to turn the car over, not knowing it was in gear.

manifold? Or the one in the y-pipe? Don't feel alone . . . I'm having a
bear of a time getting the one off the exhaust manifold - and I have that
manifold OFF the car.
Here's the O2 sensor in the exhaust manifold (off the car) - notice that there is
a ridge of metal which will not allow a boxed-end wrench on it (well, the boxed
end I have - come to think of it, you cant anyway because of the O2 plug).

Here's another angle - you can see it better here:

Snap on sells a nice O2 socket that is partly open along the side so you can get it over the sensor and gives a spot for the wire to stick out. It works great in most cases but i think when I got mine it was about $85 for it and that was about 2 years ago. I will try to remeber to get the part number tomorrow while I am at the shop
