i got a 2003 f-250 4x4 crew cab lariat an 02/03 truck which had the bad idle, no power and blue smoke it had many problems first they changed the injectors in it and did not do nothing so they done many many updates to the computer like 20 or more and they got fixed in march of 2004 they said if this last update did not fix it they would buy us a 2004 truck same everything but they fixed it and kind of mad me mad but they did give me and extended warranty. It still isnt completely fixed but now it is because i put a superchip max microtuner on it a 1704 and it runs great 510hp/800lb/ft and a 4 inch exhasut from turbo back no muffler no cat and no ressinator.

Hate to burst the bubble, but there is no PI on the current 6.0's. They open the EGR valve at idle to help reduce the noise at idle. Here is another Ford bulletin:
Normal EGR Valve Operation--Open at Idle:
Trucks built after 9-30-03 and those truck reprogrammed with WDS version 27.9 or higher will now have the EGR valve open at idle. This is to reduce engine noise at idle that has occured from removing the pilot injection. When diagnosing the EGR valve it is normal for the valve position value (EGRVP) to not change until the EGR duty cycle is greater than 30%. Broadcast Message 1067.
