start the car and let it run for approx 2-3 minutes, the manifold will warm up and you can easily remove the O2 sensor.

I'd replace easily with hopefully... but that's a decent plan. I'd also get some PB blaster and the right socket for the job, which many auto parts stores will lend you.

I've never seen stripped threads on an O2 sensor bung. They're usually really hard metal.

Is this sensor easy to access? On the toughest one I ever faced, I knocked the sensor body off with a hammer and used a 22mm socket with a 4 ft breaker bar. That worked nicely.

If, on the other hand, the sensor is hard to reach and requires a u-joint or a crowfoot, you might be in for a lot more work.

If this is a car that you think you will keep long enough to do this job again, get an M18-1.5 tap to clean out the threads before installing the new one. Don't forget the anti-seize if the new sensor doesn't already have it.

This tool will get it out with no problems.
I have used this to get some real 10 yr old bears out.

I had this same problem when it came to removing a friend of mines O2 sensor on his jeep grand Cherokee. I sprayed CRC Freeze Off which really helped then "cheated" by using a second wrench to give me more leverage on the first. http://www.autobarn.net/freeze-off-super-penetrant.html
