I have a 2000 f250 powerstroke it started kicking ses light and running on 4 cylinders. I changed cps and both uvc and the idm truck still running on 4 i can rev it to 3000 rpm and the light goes out and it starts running fine for about 2 minutes then it starts all over. anyone please help me dont know what else to do.

 

Have replaced cps,both uvc and idm this stuff is pretty costly truck still running on 4 please help. thanks

 

Miles on the truck? Any mods? Gauges?

Have you checked the under valve cover gaskets?

What codes are you getting?

 

mine had your symptoms and it was the passenger under the valve cover harness...the whole pass side injectors werent working. started intermittingly, then it did it all the time. i changed all the stuff you did b/c i had it available, but it was the wiring..

 

Do you have access to a scanner? Can you get us some codes?
