I pulled the injectors for test and clean and to no surprise to Pro-Flo
it had the wrong pintle caps installed. It came from the factory with
39mm orfice and should be a 21mm. Had them cleaned new pintle caps of
correct size, reinstalled have my power back with no hesitation or
backfire. The 39mm may have ruined my cats yet they haven't set a code.
I still get this annoying stutter at highway speeds. After doing some
research I find the stutter may be in the transmission do to a dirty
filter or speed sensor. Anyone ever expierence what feels like a miss
but it is associated with the transmission?
