Okay so i got 110,000 miles on my truck and run fuel additive in every tank pretty much. My issue is that my engine goes running perfect: balance rates in check, sounds good, no diesel in out or white smoke. But then at random times i will get engine knock at idle and a bad balance rate of about 8 on one injector. but doesnt really smoke white except a slight haze when cold under slight acceleration, not idle). But then 10 minutes later it runs fine again... my question is how long can i run this until serious engine issues. i just put in my new trans and dont want to spend a couple more thousand till at least Christmas hopefully. Any knowledge is appreciated...

mine does ALMOST the same thing, no idle smoke, no diesel in oil, balance rates are well within spec. my one funky one jumps to about 4 randomly - just a little under acceleration randomly when its warming up

there was a thread on here the other day about the FPR possibly causing this. havent had time to check mine yet.

throwing an ADII on mine today, i'm sure that will tell me if the FPR is bad as a few guys have said their lift pump showed a weak FPR. We'll see :D

Okay let me know what you find... I hope it's not an injector cause I only have about 60,xxxx miles on these injectors. I forgot that my Injectors were change when I bought the truck.
