I've read up on some discussions and have noticed that when your maf is going bad it typically reads lower... but that's not the case with my MAF.
I currently have a P0171 code and have noticed that my MAF reads above 31 g/s upon acceleration or while on the highway. At idle it reads 3.7 g/s. The highest reading i've recorded so far is when i decelerated on the highway and tried to accelerate again (lack of power/acceleration) and it got up to 59.7 g/s. This is the fuel trim data for that exact moment below.
STFT Bank 1: -10.16%
LTFT Bank 1: 8.59%
STFT Bank 2: -4.7%
LTFT Bank 2: -2.3%
MAF Reading: 59.7 g/s
Engine Power: 71.8hp (sad face)
Engine Torque: 104.5 lb-ft
Engine RPM: 3610.0 rpm
Vehicle Speed: 41.0 mph
I've read the fuel trim discussions created and haven't found anything really related to my issue.. maybe i didn't look hard enough i don't know but I just need help.
