I have a 2004 ford f350 4x4 with 6.0.

Started it yesterday, put it in gear and could not get enough rpm's to move it. Put it in park and it did not rev up very fast once I got it to around 2500 rpm it up respond. Tried putting it in gear with rpm's up, but the rpms would drop as soon as I jerked it in gear.

It is not throwing any codes, anyone know what the problem could be?

thanks
Alton

 

Check your turbo ducting. Sounds as though you have a duct blown off.

 

Try posting in the 6.0 section
