2010 A4 2.0T
Everything on my car is stock except the High flow cat. HFC is CTS.
The problem I'm having is that no matter what whether daily driving or WOT, my LTFTs are always in the 4.3-5.9 range. I've checked over the entire car, in terms of exhaust leaks, defective fueling, changed the coils and spark plugs (Gapped to .27) and I still can't seem to remedy a solution to my problem. Even giving it more fuel everywhere hasn't worked and I'm at a point where I don't know what to do. Is there anyone who knows of any links or has any advice to fix this issue I'm having?
Any parameters I might have missed?
Attached are 2 logs. One more lean than the other.
