First thread here!2000 F250 7.3 4x4 auto. Truck has benn running fine until yesterday morning, started up fine then started missing w/SES light on.went to local parts house to scan and no codes. Went out and bought a DS tuner and got p1316,0470,0478 codes.Removed both valve covers and started pulling inj. wires off with it running and found one inj. that didn't change the sound of engine rpm and replaced it.Put on one new valve cover harness and thought it would be fixed.WRONG. Still right where I started.I also did Guzzel's fix for EBP valve but didn't replace sensor,dealer closed on sunday, Thanks Guzzel ! Please Help me.

P1316 is injector drive module codes detected. P0470 is Exhaust pressure sensor, P0478 exhaust pressure control valve high.

You might have a bad injector drive module. Which could be causing your engine running rough. The codes could be a result from how your engine is running.

I would do more diagnostic to the truck before replacing stuff.

I do not know, you would have to ask a tech about that.

Found a good and easy way to diagnose code P1316.I had a bad Injector #6 and a bad UVC harness,the bad harness was a brand new one,put old one back on.Troubleshoot using this link and maybe you wont have to do it twice!..P.S. you can check the injectors by puliing leads off one at a time carefully. 110 volts.I used sparkplug boot pliers.
