    Aloha,
    I recently have been getting the p0171 code for my tacoma. A little while ago the line to my maf was broken from my airbox and it was running, but I recently jb plastic welded the crack to actually use the airbox and cleaned the maf. now the truck has been running poorly. Code has been coming up and when I hit about 3500-4500 RPMs my truck begings to feel like there is no power. Please feel free to leave suggestions on what the problems could be and what I would have to buy and fix.
    Mahalo!

    P0171 can be caused by a lot of things. Try looking for a vacuum leak somewhere. Spray starter fluid near vacuum fittings and listen for an increase in idle.

    MAF could be bad too. Try testing it with a multimeter against the Factory Service Manual data.
