UPDATE:
If you can't get the an o2 sensor out, it is probably because you are trying to remove it after the exhaust manifold has cooled down. The manifold needs to be heated to remove the sensors. Either heat it with a torch, or run the car to heat up the exhaust before attempting to remove.
I ended up only installing one o2 sensor and drove the car until I could get a new one. I had a CEL but the car ran fine.

Installed my headers and got everything 90% back together and I can't even get the O2 sensor to break loose with a pipe wrench and a 4' breaker bar.

So now I'll have to wait and see if my local GM dealer has one in stock on Monday.

Anyone have any ideas? I'm guessing it's a bad idea to start it up without it. Any help?
