04 6.0 Question
I have an 04 F350 with the 6.0 in it and the guys (work truck) have been saying it runs like crap when its cold, i took it into ford yesterday for an oil change and got them to change the fuel filters at the same time. When i went back to get it later in the day the truck had been sitting for 3-4 hours and was cold. I started it up and let it run for a few mins befor pulling out on to the road, when i tried to speed up the truck had NO power and would barely even move so i had to pull over and let it warm up some more. After another couple of mins i drove away and it seemed normal. What would be the cause of this? the truck has about 200k on it and has no check engine light on. Runs like a champ when warm but really crappy in the morning, stalling and sounds like its missing.

There is a new flash out for this that warms up the oil around the spool valve in the injector. Here is a link to the TSB

Seeing that you are a Canuck, it is pretty important that you use 10W30 in the colder seasons, if not year round. Using 15W40 in the winter, late fall and early spring will cause cold start fuel injector issues if you are using conventional oil.

Some vehicles equipped with a 6.0L diesel engine may experience white smoke, lack of power, exhaust odor, surges, running rough, or no start when cold. These conditions are caused by the injector spool valve sticking internally during cold engine operation (engine oil temperature (EOT) less than 70 °F ( 21 °C)) . The concern is typically evident following a cold start after an overnight soak at ambient temperatures below 70 °F (21 °C). and may last 3-5 minutes or longer as the vehicle warms up. The concern completely disappears after driving and the EOT is greater than 150 °F (66 °C). This concern typically occurs on vehicles with greater than 15,000 miles (24,140 Km/h).
It sounds kind of like what you have going on. The inductive heating fuel injector flash is supposed to help get the injectors up to temperature much quicker than the old flash. Keep in mind that you may still have some fuel injector issues that the new flash may or may not remedy.
