Did you swap coil packs from bank 1 and bank 2 to see if the misfire moves? If you find that it is an o2 sensor, precat, I just returned a new one to the pepboys on industrial near fftec. It's the same bosch one as oem. So they will have it in stock. Good luck and us know the update.

Thanks for the info (to everyone else as well).
If we can't trace it down to anything else, we'll swap the coils to see if it moves. Should have some more details this afternoon.
