Do all Diesels lack power after a cold start up?
Or is this something else? It sat all day and night. I cranked it up and headed down the road. It hardly had any power until it got warmed up...then she ran like a top. Just curious. Thanks for any info!
Its a 2003 F250 FX4 6.0 Turbo Automatic.....

How cold are you talking?
I had a similar experience one time over the winter when it was -20°F, the truck was really sluggish and would only get up to about 30mph. You could put the pedal to the floor and it just wouldn't do anything. Only lasted a minute or so and then everything was fine. I think the oil was just so thick from the extreme cold the injectors weren't working right.
If it is doing this in weather above freezing then I think there is something wrong.

I find I don't have much power after a cold winter start. I came home from a business trip this past winter. While I was away, there was a thaw followed by a deep freeze (below 0 F). My tires where frozen to the pavement of the airport parking lot by about two inches of ice. Until the engine warmed up a little, I could not break free from the ice.

Well I should be more specific when I say cold. I meant the motor hasnt ran in 18-20hrs and I live in North Texas. Roughly 80 degrees when I started it, put it in drive and went. Felt like I think a Chevy would................NADA.....I let it sit the same amount of time today, cranked it up and let it idle for a few minutes and off she went like normal.

If it was 80 degrees out and did that then I am afraid you may be starting to see injector stiction issues. Do you have either of the latter two flashes that add the buzz after shutdown or heat the injector sppols?
You may want to check out the thread about Hot Shot Secret. This supposedly is designed specifically to hep with injector stiction issues.

Ive only had the truck for about 10 days. It has 80,000 miles on it. The guy I bought it from claimed he changed the oil every 5,000 miles (who knows) I do know it needs to be changed right now, its about 100 miles over 5000.

The "buzz strategy", cycles the spool valves to eliminate any oil that has pooled around them, when you turn the truck off and you hear a buzzing sound for about 30 seconds while this process is ongoing.
The "inductive heat strategy" uses electicity to heat the injectors and oil around the spool valve when the truck key is turned to on and continues this process for about 2 minutes after the engine is started.
Both strategies accomplish the same thing in different ways. IH still uses the "buzz" strategy in there trucks and FMC switched to the "inductive heat" strategy.
