17522 - O2S: B1 S2: Internal Resistance too High
35-10 - - - Intermittent

I've been getting misfiring at WOT ~15psi+, plugs are new, gapped to .028, everything on the boost gauge is reading fine. I ran the VAG and found that code. Then I let it misfire enough to through a CEL and i've got misfiring in Cylinder 1 and "random multiple misfires." I'm going to try the "switch the coil pack and see if the misfire follows" trick, but I wanted to see what people have done about that 02 code.
