Trying to pinpoint a starting place. The issue:
-Hesitation/Bogging during medium to hard acceleration
-Idle fluctuation especially at startup
-SES on, throwing codes:
p0171 system too lean (bank 1)
p0174 system too lean (bank 2)
When I accelerate med to hard it bogs initially for a second or two, then seems to catch itself and accelerate normally. Almost feels like its misfiring sometimes. Replaced the fuel filter and ran great for a few days, then problem slowly persisted.
I'm thinking fuel pump or bad injector? or intake leak?
Appreciate the input.
