Well it has finally come to the time where i got the error 41 code.
After checking the 02 sensor with a DVM it is definately dead.

After a few douses with PB Blaster the sensor was still being a total
pain to get out, and after a quarter of the way i noticed the threads
had a small flat spot on it. Now should i just try and get the sensor
the rest of the way out not knowing how bad it is, try and tap the
threads, and install the new one? Or take it to a shop? Any help would
be appreciated since i would like to do this myself.

Cheers,

I would take the sensor all the way out and inspect the threads in the
manifold. *You* won't cause any more damage removing the sensor than
would someone at a shop.

If the threads are damaged, you could clean them out with a tap, drill
out and put in a helicoil or just jam the new sensor in there, as the
car will likely be made into 5-penny finish nails before needing another
O2 sensor.
