Hey guys Ive been having some injector problems in the last couple of months. Its not a Harrness or connector problem either. Back in dec i got #6 repalced with a new bosch reman because it had a +5.5 rate. Now im having a bad knock under easy acceleration. WOT no noise, only knocks when engine is at operating temp. I know its coming from the drivers side. I can put diesel kleen in and the knock will go away but as soon as i fill up without using additive the knock comes back and it sounds terrible. Heres a look at my rates at operation temp. Im Guessing its either #6 or #8.. Any ideas guys? would a leaky inj cause a knock or a sticking closed inj cause a knock? Im guessing my #6 inj i just replaced took a shit after only 3k.
