First set of new injectors from dap, had to send back for warranty, put 2nd set in then had to do the same thing again. With this being the 3rd set am I just having really bad luck with injectors or is something else causing it?
I keep getting a knock/ping and sounds like a bad miss if u (more prominently)coast and very lightly tap or ride the throttle and just runs rough/ just not how it should. Runs rough and knocks when normal driving the same just more so as stated above.
Why do I keep getting this knock etc? Is the vp44 causing this to go down stream? Fuel psi is consistently 16psi, no codes or check engine light (doesn't mean awhole lot but..)
This has all been in a very very short period of time. The last thing added was the quadzilla adrenaline but I don't see it being any issue?
Only things I can think of is 1- injection pump (runs great) 2- injector lines or tube (mating surfaces looked good) 3- just getting bad injectors.
What the heck?
