How complicated is it to change the injectors on my 99 7.3? I say that because it has a deff miss goin on and its smoking at idle it's faint though so I can't tell color but if u gas on it at idle it's ablack white color. It's been running bad not much power now. It has 552 n some on the original injectors so I say they are pretty worn out. I'm new to the powerstrokes so any help/adcive would be great.

 

Injector swap is pretty easy. It's about a 6-8 hour job

 

Any special tools?

 

No, just you pretty basic hand tools. I think there is a write up on here somewhere on how to do it.
