SO as you can read, I have a bit of a conundrum. The Pre-cat o2 sensor broke off at the top of the bung, and i can not seem to get a good enough grip to unscrew it. Pipe is currently off the car (long story), and I have soaked what is left in WD 40 to see if that might help. Obviously, I will be replacing the sensor, but does anyone have any good ideas on how to get the friggin' thing out?

Any help is greatly appreciated.




I'll eventually take the time to put something here. I swear.
