Since my rear 02 is turned off in my tune, I swapped my front to my rear on the O2, but no change. Guess I can try swapping left to right now... otherwise it may be time for the long screwdriver and hammer catalyst removing technique. If it really is plugged... I wonder how it happened so suddenly.

Thats why I put the unused #2 O2 sensor in its place, I'm guessing both aren't bad.
