My b1-s1 and b2-s1 O2's threw low voltage codes at the same time. I hooked my shop's Solus scanner to it, the O2's are sweeping normally. I took a look at the misfire history, Cyl's 1,3,5,7 are normal but cyl's 2,4,6,8 have hundreds of misfires each. 3 weeks ago the misfire history was normal on all 8. I am not lacking power and have normal idle quality. Plugs and wires are all relatively new, just inspected them and they are still good. Everything else is normal. Thought it could have been a possible bad tank of gas but this happened over 2 tanks from BP stations 100 miles apart.

What would cause this undetectable, mass misfire on only the right bank and why would it throw o2 codes on both banks.

check your misfire thresholds...don't know what else to tell ya.

i did a cam swap and my cam specs have been associated with having to mess with the misfire thresholds
