05 f350 back in the shop

I had a jasper engine installed in my truck back in june, and so far its been nothing but trouble its supposed to be a basically new engine its been in the shop twice and each time its because of the fuel injectors going bad and they originally put new injectors in when we bought the engine. And to add to all the inconvenience jasper says its not there fault and they will only pay up to 60 bucks an hour for labor you cant go anywhere in california and have your car serviced for 60 bucks an hour. idk if anyone else has dealt with jasper engines but i wouldnt recommend getting an engine from them

use rev x oil additive and change to synthetic oil. This cures injector stiction. The spool valves on the injectors get gunked up with soot and deposits from Dino/conventional oil and kill injectors and making it run like crap. Also make sure the FICM is good voltage to the injectors. A failing FICM doesnt send proper voltage to the injector units to fire them properly....

any more questions post up, ill subscribe to this thread, im sure other will have opinions as well. Hopefully we'll get this figured out for you

Low fuel pressure will also kill injectors. If the psi drops below 45psi from idle to WOT, your causing damage to the injectors.
