Also check to see if the yellow paint on the throttle part of the right TB. If any of them have moved then that could be it.

IIRC, you would only add an O2 sensor for the auto tune on a PCV. I thought that was a second sensor (like you would have one on each header and the y-pipe on a car), but my stock exhaust doesn't have one at all.
