So tonight driving around after swapping bad O2’s i noticed with cruise on the afr was constantly bouncing from 13.4ish to 15.2ish also a pretty steady misfire type noise in the exhaust tone and when i would just roll into the throtte afr would just climb to 18. Didnt have HPT to log this, but i need to watch the new O2’s and verify they are working correctly first off. But other than that, what else should i look at?

Im thinking maybe i should pull the plugs. What about injectors? Wouldnt this be a sign of a possible faulty injector?

I do not have another sensor to check against my current sensor for wideband.
