Hey guys,
So I've noticed when driving on the highway, when I let go of the gas after accelerating it will sometimes burn lean, not a little bit and for a second, it goes to the limit (my Analog wideband goes to 20) and it stays there until I accelerate or start giving it gas to maintain speed. Today I was paying more attention to it and I noticed it only did it around the 2500 RPM range, if I accelerated the car and I let go of the gas and it lands on 3000+ rpm it doesn't lean out that high, it will lean a little bit like you would expect but it will correct itself, but if I let go of the gas and its around 2500 RPM it leans out to 20. Anyways I've been thinking what can be causing this? at first I thought maybe its time to change the fuel filter but then I thought thats probably not it because under acceleration it richens up between 12-10 (10 is a bit extreme) so now I'm thinking maybe its the MAF. The drivetrain is stock and the 13c turbo is putting out 5PSI.
Thanks for the input!
