Usually when that code shows up it means it's time to walk. The CMP (CPS) is the sensor the computer uses to read the timing of the engine to determine injector firing etc. Any other codes show up like P1316?
For the code, get yourself a new CPS from Ford (don't waste your time with the parts house versions). Then I'd also consider checking your UVCH connections for burnt pins since those can give off the rough running symptoms you're describing.

Yes. It's the sensor that has the thing that looks like the timing mark at the crank.
Different year motor, but this shows how to change it. Welcome to guzzle's CPS R&R Web Page<
Should be around $25 or so from the Ford house.

A $30 sensor is hardly a reason to trade the truck in. (unless you want to make me a good deal on yours
) The only CPS failure I've had on my current truck happened around 155,000 miles on the odometer. I've over 398,000 now. No reason at all to trade the truck in.
