    Looks like the Dorman gaskets that were on my POS Dorman intake.

    My 2003 5.4 fuel rail looked the same (I just replaced my intake). The vacuum line is for the fuel regulator. I would replace the intake if it has any kind of distortion.

    New gaskets in. short term and long term trim dropped below 30% but still set off p0174. idle got way better and can rev rpms higher.

    maf sensor seems to be a culprit.? could it be possible? how can i diagnose.

    just got hit with a tensioner tick. **** timing chain rehaul soon too.
