so i have noticed that at idle the af learning drops to as low as -42 and at normal driving its around -15 to -20. the other day it threw a cel for p0172 ( system too rich). randomly, when i stop at a light the engine will bog in rpms and idle rough but if i blurp the gas itll go back to normal.

Sounds like a warranty question. I’d take it to the dealer.

Lol warranty is out of the question. Full bolt ons except headers and turbo and flex fuel
That’s great information to include in your original post.

Sounds like he never got it tuned
My car did the same thing right after a dyno tune. I took my car right back to the tuner to correct it. He said the car never showed those AF learning numbers while on the dyno, but did on the road.
