6.0 pulling problems

I have a 2003 f-350 6.0 that doesn't pull very good from a dead stop. After you get going it does great. Any one know what I should check? I was turning around the other day and the front wheel ran of in a little ditch and the truck wouldn't even spin the tires.

These trucks produce their low end grunt a little higher in the rpm's than the 7.3L or the competition. They like to play in the higher rpm's. If it wouldnt do that then you may have a problem.

I'm going to say you are probably experiencing turbo issues. Can you get your hands on a boost gauge to see what kind of boost you are getting?

Injectors maybe? I had similar issues on my '04, turbo lag was unreal, especially when cold. 4 new injectors and it felt like a brand new engine.

When was the last fuel filter change? If its been awhile might try that. fuel pressure has a lot to do with power problems with 6.0

If youre filters are good look at the intercooler hoses, they can develop leaks and will cause a significant power loss

Just had all the filters changed. The only time it is sluggish is from a dead stop and on cold start ups.

I'll bet good money, very good money, that you have bad injectors. That is exactly what my issue was.
