Can a MAF give a good reading at idle but then not really respond well as more air is introduced, showing less air that is coming in?
Took my car for a ride last night after having my fuel filter/pressure regulator replaced.
What I have been seeing after the wire repair is barely any adjustments in LTFT when I am mostly idle or doing local driving.
When on highway, steady driving. LTFT goes to 2.13-3.19 ish. Bank 1 is lower than bank two. But after the fuel filter replacement, the LTFT has been even in both banks. but still around 2.13-3.0. when i get off highway, the LTFT starts to drop.
This could be normal but I am not sure. I'm also planning on either replacing my fuel injectors or cleaning. I may just replace as they are original from 2001 and I am trying to overhaul as much as I can.
