P0603 Code???

SCMT- Super Chips Micro Tuner

P0603 is harmless, it just means the KAM was turned off when you erased the stock program and installed the SCMT programs.

P1316 is the one causing your truck to run poorly. It could be caused by the UVC harness. UVC-under valve cover harness. The injectors on your motor are under the valve cover. The wiring that goes to them passes through the valve cover gasket/harness. Its a normal problem on these engines for the UVC to go bad. Usually when they do they can by easily identified by removing the oil filler cap on the passenger side valve cover and smelling it. They usually leave a trace of a burnt wire smell. That's the most common trouble to check first.

A few months ago I had a member come by my house with the same symptoms and same code, and it was found to be an injector had become unplugged and the truck was running on 7 cylinders. This is NOT common though. Check your UVC harness. It may sound complicated buts it's really not, they are rubber gaskets that use no sealant.

Your truck will be reliable don't worry, and welcome to the forum.

I meant to say all that in my first post, but I had a cold maragarita waiting for me elsewhere.

Thanks for covering my back Bryan.

Thanks for all of the info on my problem. Sat. AM I stopped by my local Ford dealer to talk to one of their diesel tech's. As it truned out I had taught the guy science when he was in the 8th grade!! He suggested changing both gasket/harness out while it was apart and even told the parts guy to give me a break on the cost. The drivers side was a LOT easier than the passenger side due to 'clearence issues' but all in all it was an EZ fix. I just wish it haden't cost 299 bucks.
She's running GREAT now and I hope I have no more problems. As I said in my first post this is my 'first Ford' having driven Toyotas since 89. I hope the Super Duty will be as reliable as the Yotas I have owned. But, just in case I'm going this week to get a CPS, from International, to stash in my glove box so I will be ready 'when' mine goes south.
Thanks again for all of the help guys.
