No, none.
You're going to have to cough up a little more info...
I'm assuming it's an 04...any codes? Does it do it just when it's cold, or when it's warmed up too? Is your oil and filters fresh? Has the truck been reflashed lately? Egr valve cleaned? Is there excessive smoke out the exhaust?

No codes? Try testing the ficm, instructions in the tech folder. Remember to wait until the glow plugs go off to check running voltage. If it checks out ok, a cheap trial would be to throw some rev-x or similar into it to cure injector stiction. Since it's still running good, try cheap do it yourself stuff, then go on to a dedicated scan from a dealer or a good scanner like auto enginunity. There may be codes stored that a generic code scanner won't pick up. (Can't wait to get mine...)
