only started doin this recently...

once warm runs like a champ..help me pleassse

Sounds like a FICM issue. Fuel injection control module, search for FICM and you'll find gobs of information. Also, search swamps diesel for a write up and testing your FICM or www.circuitboardmedics.com.

Good luck. If bad FICM, don't buy from Ford, use one of the places that fix them vs buying factory new.

Cheers.

FICM or injector stiction. Check the voltage on the FICM when cranking over and when running (test when truck is cold) If the voltage drops below 46v then the FICM is toast. Send it to Swamps Diesel and get a 58v FICM. If the FICM is good add 2 bottles of Rev-X to the oil. REV-X Oil Additive | Diesel Fuel Additive | High Performance Oil That should clear up any stiction issues.

Be anal about maintenance. Oil changes at 5k with 5w40 synthetic and use Motorcraft or Racor filters. Racor makes the Motorcraft filters and are cheaper. Fuel filters every other oil change.
