So I’ve been having troubleshooting why my afr2 and trim when monitoring it on my jb4 app. First off my car is a 335i n54 single turbo, and I’m having issues with the afr2 reading back and forth, for example at a stand still if I was to rev it to around 2000rpm the afr2 reading would go crazy would jump from like 12 all the way to 18, same goes for the trim would do the same thing as well as the rpm needle will not stay still it would try to go up and down even though I am not moving the gas pedal. All while my afr1 is solid pretty much. I replaced both of the bank 2 sensor front and back and still nothing. Any help would be awesome, forgot to me mention while at wot both of the afrs look solid though.
