I have a 2006 ford escape hybrid (4wd w/o TPMS) that has the P0171 code rn. I replaced the MAF sensor to try and fix it, but it didn't work. Also thinking about replacing vacuum tubes, and checking the O2 sensor, fuel filter, & fuel injectors. One shop near me that I trust (Courtesy Auto Service & Tire - Lacey, WA) couldn't find any issues. Anyone have and suggestions on repairs? Whether it be DIY or not.
Vacuum tubes?
okie, I have aquired a PCV valve from AAP. How difficult would a self repair b? Other parts I have aquired recently that may or may not help my code fixing include a fuel filter, and 4 fuel injectors. Also a air filter but that prob has nothing to do with it lol. I tried pulling a vacuum tube from the same wrecked ford escape hybrid in the junkyard that i got the rest of my parts(not the pcv valve obv) from, but it didnt wanna come out n i didnt wanna break it, so i left it.
