injector problems!

[keevinzanejohnson]

I just recently replaced with my original cp3 with a custom built by shane at wicked diesels. But I have a few questions. I know I atleast have one injector that isnt firing right. So can I just change out the nozzles and be alright or do I need to replace the injectors as a whole?

why is it not firing right most of the time if its not firing or working properly its the body not the nozzle better be safe than sorry you can pull it out an send it off to b tested if uyou can have your truck down for a ew days then you will know but i have never seen a nozzle go bad.
