Ok super techs! I am running out of ideas. I keep throwing a 1316 and 1211 code. Injectors are less than 6 months old ( factory reman). Changed valve cover wire harnesses and gaskets, changed fuel filter, IDM and CPS. Seems the truck is running rough. CEL stays on or flickers. Any help is greatly appreciated as this vehicle puts food on the table.

 

was bumming around on the net and came across this might help you
