Hi guys i am new here i just need some help for the past 3 months have have had really bad fuel economy, i thought it maybe could be leaky injectors looking at the logs i saw my bank 1 AFRs were slower to respond so i brought 3 new index 12s injectors for bank 1 coded them and reset adaptations using ista still no improvement.
I was thinking maybe it could be the secondary O2 sensors they don't seem very stable to me and the LTFT for bank 1 is always in the negative the STFT looks fine to me never really maxed out. what do you think it could be possibly post cat O2 sensors, pre cat O2 sensors or something different altogether.
mods
stepped intercooler
stage 1+
93 octane
any help would be appreciated
