Re: Codes p0171 and p0174
i spoke too soon. before i replaced my o2 sensors (weekend before christmas) my light came on about 3 times a week. it hasnt came on since till last night. so i will look into the filler neck. i fixed it when i first bought the truck 1 1/2 years ago. so it could be i missed something.
things to check also for these codes: mass air flow sensor, vacuum leaks, pcv valve/lines, leaks in the intake tube after MAF, actually a lot of things can throw these codes (thanks ford).
