Here we go a friend of mine is having a problem his 7.3 it has a miss?pulled the injectors no change.broke all the lines loose 1 at a time no change it seems to be a miss on no particular cylinder but a miss no fuel leak or air that I can tell it's driving me nuts.

 

so you did change all the injectors??? is it blue smoking bad??? could be bad rings or a burnt valve......

 

had the injectors checked no change have to ask about the smoking.

 

Yah, ask about any smoking, codes, oil leaks, etc...

 

CODES!!!!! WE DONT NEED NO STINKIN CODES!!!!!!

not a whole lotta codes id say on a mechanically injected 7.3........

 

, nope no codes.

So when u cracked the injector lines there wasent a cylinder that made no difference at all? (u know, u crack a line on a good firing cylinder it misses worse, then u crack a line on the bad one it makes no change in idle)

I would be suspisious of a bad IP if all 8 are in fact firing. U said u had the injectors tested, pop tested at a diesel shop im assuming? did u have them reset to factory specs?

I chased an air leak for over a year before i found it, my truck would loose prime after a few hours of setting. How does it start, after a night of setting?? How much fuel is in it? does it do it both full and at 1/8th tank??
