Removing O2 sensor...is it possible?
So I need to replace the O2 sensor on my '93. It's the original sensor and it has outlasted one crumbled frame already. So needless to say it is RUSTED. Best I got to heat it with is a MAPP torch, no oxy available to me. I've got the O2 sockets I need but I've already tried those and it's a sure thing that I'm going to need heat. You guys have any success getting it out with a MAPP torch?
My alternative is that I do have a welder so theoretically...I could weld a new bung in. I'd really rather not do that though.

Once you're up to operating temp and the oxygen sensor can be trusted you enter closed loop mode, where it injects a set amount of fuel based on the table, and the oxygen sensor can then say whether it was to rich, lean or just right. Then it will trim your fuel tables to adjust how much fuel is injected to get the leaner mixture possible for the given conditions.
Without an oxygen sensor you'll most likely run but run quite rich at all times. In the end you can test it out yourself just unplug it and see how it runs Although I wouldn't recommend running without one unless you enjoy buying fuel

So this is with a swapped motor, V8 318 replacing the V6 that was in here. The V6 had a stalling issue. When I would push the clutch in sometimes the rpms would drop and the engine would die. I could rev it a couple times to keep it running.
Now the same exact problem is occuring with the V8, same frequency, same symptoms. The kicker is that ALL of the engine bay wiring harness and PCM is from the V8. That leaves the O2 and 4x4 sensors as basically the only electrical components remaining from the V6. And the V8 donor truck had no such stalling tendencies. That on top of an intermittent check engine light which-surprise surprise-is an O2 code, I'm reasonably certain that the O2 sensor is causing my stalling issue. Gotta get the darn thing out. Thanks for your suggestions guys. I have a full O2 sensor socket set but I need to add heat and penetrating oil too.
