My truck is still doing the bucking around thing at low throttle position while cruising down the interstate. I'm starting to think maybe injectors. Does anyone know of a good descriptive article on just how these injectors work and how to work on them/adjust them? I want to completely understand the basic operation of them before pulling them and checking them out.

got any codes?A miss caused by the IP will usually set a code.
I doubt the inj are causing it,air in the fuel system however might.
A bad inj will show up more at idle and cause knocking.

Your PMD can cause it too,sets seldom a code.

That is a nice truck.

Is the turbo still using the vacuum system?

Check your air filter?

Not throwing any codes at all.

Talked to a diesel mechanic today that seemed to think the IP was the problem. I'm just not sure yet. Tomorrow i'm going to check and see if the scribe mark on the IP is in the right place. Then might start checking for possible air leaks in the lines.

hey man my 99 is doing the same thing but mine will stop after a few miles, mine only does it around 70mph if you mash on it it stops missin and goes on. i got some hot shot secret to try and clean the injectors ill let u know if that works ive seen that stuff fix many diesel injectors. let me know if you find out anything else
