I started my truck yesterday and while at idle the rpm's drop and the truck acted like it was going to die and then went back to normal. Ran the scanner on it and pull the following codes:

P0264
P0265
P0267
P0268
P0273
P0274
P0282
P0283
Any idea what could have went wrong. I cleared the codes and the only one that keeps coming back is P0274. Any Ideas.

 

try pulling your EGR valve out and see if it's not clogged with soot..I've had that happen..now i'm out there doing a EGR DELETE...

 

Saturday I started the truck for the first time that day and after if ran for about 20 seconds it just shut off. I would start again and run fine. It happend again Sunday evening. Start the truck, run for about 15-20 seconds then die. Would always start again and run fine.

 

Very likely a FICM failure, flash at best.IMHO http://dan.prxy.org/Truck/6L_bible_h...l/Page_94.html

 

Just a update on what the problems turn out to be. About a month ago the Ford Dealership replaced my FICM and two injecters (#4 & #8). I took my truck back to them last week and they searched and found that the pins in the FICM harness were bent or damage when the FICM was replaced. So they repaired damage and go the truck back running with no charge. They accepted the damage as their fault and no charge for the fix. I have had the truck to my dealer 3 times in the 3 years that I have owned the truck and they have been real good about the work and getting the truck back to me quick.
