Rough running

[coleyslawn]

I am starting to have a few problems with my diesel running pretty rough and I hope yall can help me. The truck has 180,000 miles and still has the original glow plugs, injectors, and injector pump in it. It really smokes (Blue smoke) while idling or while driving and sometimes after it starts up (especially after it has warmed)it will stall or sound like it has air in the system.
There are no visible fuel leaks anywhere. The fuel mileage and the pulling power have literally gone to nothing. What do I need to do to get this thing back to where it needs to be? I think I am going to get a new pump,injectors, and glow plugs just becouse it seems to be the christian thing to do but is there anything else I need to address?
Also, where is the best place to get pumps, injectors,etc.? I have had folks around here tell me many diffrent things and I am so mixed up that I will just leave it up to you, the experts. I read this board very often and everyones posts have really helped me even though I very rarely ask a question. Sorry for the long post. I look foreward to reading everyones responses.
Thank you,
Jr

I would advise a double dose of Power Service or Stanandyne fuel additive if no improvement seen, then think about new injectors, return line kit and injection pump....... your due.
