Did you try sticking a flathead screwdriver under the edge of the socket and undoing it while twisting the flathead? Like a drywall screw comes out?

Has anyone ever tried drilling a hole in the sensor large enough to get a screwdriver or something through it and torque it out that way? Curious if that might work or if it would just tear it apart. Im letting it run for about 5 mins or so before trying a pipe wrench now. Still open to all suggestions.

*sigh*
Don't heat the sensor. Heat the mounting point. Apply big pipe wrench.
Pipe wrench. Not Vice-Grips.

Mcguiver....Why not approach a muffler shop, (newO2, sensor in hand), and get an estament? Might be on par with the cost of the big easy out you might try next.

Agreed. Don't heat, (expand), the problem, expand the hole it's screwed into. If you got all hot then cooled the sensor with Freon might help.
