Today I was doing some 3rd gear pulls and noticed at the top of the RPM range I would feel a noticeable hesitate and let off. After looking at the logs, I'm noticing that my AFR bank 1 shoots up to 20 (max) while AFR bank 2 stays at ~12.
Why would this be happening? Bank 1 primary sensor going out? Bank 1 injector(s) (DI or PI) not firing properly? Started happening out of the blue. No check engine light or codes. I don't really want to gamble with weird stuff happening at this power level. Hoping someone sees something I don't in these logs.
