Car - 2013 Audi S4 (no cats)
The car stumbles on acceleration but no misfire codes. Idles rough sometimes. I've replaced all 4 O2 Sensors, MAP sensors, fuel filter, injectors, plugs, crank case valve, fuel control module, and maybe a couple things I haven't thought of.
No intake or exhaust leaks.
Can someone take a look at these logs and tell me what the heck the problem might be????? Also my LTFTs rise on acceleration and Bank 1 is usually around 14% when cruising.
I've taken it everywhere and NO ONE can figure it out.
