Hi guys. My truck is running fine, just getting poor fuel mikeage (13mpg'ish). I went by Autozone and had them run the codes.
P0174 - fuel trim, bank two
P0171 - fuel trim, bank one
P1506 - IAC overspeed error
P0457 - EVAP small leak detected
I have a feeling I know what the P0457 is... I capped off the vac fittings on the underside of the upper intake. I believe they were some sort of vent from the fuel tank. ThE IAC code kinda threw me because I cleaned it out reaply well a couple of months ago. Maybe it just needs replaced? Also, are the first two codes saying I just need o2 sensors? With almost 200k on this thing I'm not suprised that they'd need replaced lol.
