Also, thought I'd toss this out there. My truck is running cutoff exhaust after the cats. When I let off the gas quickly (like passing someone) I get several pops from ( I assume) air being pulled back through the exhaust. The codes don't seem to pop when I'm getting that noise, but I thought it might be relevant

Also, mu bank 2 sensor was just nasty with mud and rust. I took 3 blue shop towels and cleaned it out the best I could. Couldn't vacuum sine I did it with the intake on.
