P0171, increase mpg?
Vehicle is a '96 Ranger, 4 cyl, 5 speed, 2WD.
I recently got a check engine light which Autozone told me is a "P0171 System too lean bank 1". I haven't confirmed this yet, but I seem to be getting better fuel mileage... I'm at around 340 miles with 1/8 tank to go, I usually get to 320 or so as I'm rolling into the gas station on E.
Has anyone ever heard of this happening? I understand there's a good chance my fuel gauge is coincidentally on the fritz, and I'm about to run out of gas... any thoughts?
