Well the shop finally got through with my dad, 2500 dollars
later his truck runs, but he said it still didn't run like
it was supposed to and shuddering, just wanted to get it
away from this shop(I'll get to that in a min.) Supposedly,
they just starting pulling injectors and found a piece of
metal that pierced an o-ring, and supposedly found #1
injector to be bad. They replaced all o-rings. Now for the
still running like crap/shuddering....dad drove it home and
had my brother look at it, pulled both valve covers etc,
checked all wiring & injectors working good except #4,
found the #4 injector unplugged! Also, the intake tube that
hooks up to the turbo now has a huge crack in it(about to
fall apart, was not like this before brought into shop). So
there you have it....HPOP(that it most likely didn't need),
injector o-rings, and 1 new injector it's running
again....after fixing wiring that was left loose. Hope this
helps somebody in the future!
