My Ford diesel when it's cold, will miss and sputter until the engine temp reaches it's normal operating temp. What's up?

Try adding a decent diesel fuel conditioner / injector cleaner to the tank before filling. Drive for a tankfull or two and you may see an improvement.

Also, this truck has a manual fuel / water seperator, right? Have you drained it recently?

Also, try changing your fuel filter, if you have not done so recently.

Fuel conditioner wont do anything for a miss. Its a HUEY injector. You more than likely have an injector going bad. If i were to guess i would say number 5. Its usually the one that goes out on 6 liters. Also when do you change your oil? Believe it or not its the most important thing you can do as preventative maintenance on a powerstroke.

How about an ''Out of truck injector service''
A diesel shop can Micro bath, blowout, and test the flow rate.

I would honestly just graph the injectors, Find out witch one it is and replace it. They aren't that bad.
