Starting to sputter when cold

[azreider]

I am sure you will diresct me to the answer. Here is my dilemma. Here in Arizona where it really does not get too cold, my '04 6.0 is starting to take some time to warm up and run smooth due to ( i am sure) sticky injectors.
Is there an oil additive to smooth this out or can you use one of those desludging additives prior to oil changes to help this issue?

Please advise.

im having the same problem and they definately said it has to do with the injectors and EGR...just got the info today so i havent tried it yet but got info that the best thing to start with is fuel additive called CITANE BOOSTER PERFOMANCE IMPROVER..you can buy it straight from a FORD Dealership! If you happen to try it let me know your input!

i had the same problem and then shortly after it started the ficm (fuel injector control module) went out now the truck runs great no rough start or loss of power

[fordmasterdieseltech]

can be a FICM issue or an injector issue. need to check your ficm voltage. any codes present?

how do you check voltage from ficm? i think mine is on the way out aswell

There's a write up it's called repairing ficm
