Injector replacement

My 1999 f350 is really acting up and I'm almost positive it's the injectors. I found injectors from injector warehouse wondering what you guys think of them? Or do you guys have other suggestions? I had #8 already replaced only need 7. I'm a novice wrench turner am I in over my head on this one I have a pretty mechanical friend help me on this one as well he but he isn't proficient with diesels. Are we setting our selves up failure?

It's really easy it only took me about 3-4 hours to do it for the first time. It would have been quicker but I was bsing with a buddy while I did it.

What makes you think the injectors are bad and need replaced?

There are MUCH cheaper things that will throw injector codes.
Like a CPS. Usually will throw a number 8 bad. There's a good chance it was ok.
UVCHs and their connections.
IDM.

That's the one I read. Cool. How was purging the system? Anything you can tell me that isn't in that right up that might be helpful?

It's been idling really rough, smoking quite a bit, there's been a lot of missing, and stalling shortly after start up almost every morning. I am cleaning the ebv valve and checking the IPR and ICP sensor tomorrow. CPS was replaced 2 years ago. Truck has 207k on it I think it's time.

Now the UVCHs is that connected to the glow plugs I think I'm going to replace the plugs as well. And the IDM isnt that kind of rare one to go out or am i mistaken? Hey your quote on the bottom about the piston rings is that true or a joke or what? I think thats what happened to this truck. This truck needs a lot of work I'm just getting started. It runs real rough right now but I can't afford anything else right now. I just went back to being self employed so I have to make due with what I have.
