I hate when threads don’t get updated.

disassembled the injectors with the “builder” I am using the term VERY loosely.
found locating pins in 2 injectors broken, hence those injectors not lined up correctly.
Haggled got labor cost returned decided I could do it myself, ordered all new o rings pulled some pins from “his “ parts.
Truck is running great.

Percent delay as I understand it.
I checked it using forscan but even without checking it was very apparent my truck was not happy, this just finally pointed me in a direction that made sense.
