W vin is 4.6 2 valve.
With that many miles, it could be a number of things. I think I'd start with pulling the spark plugs and doing a compression test. If any cylinders are low, you just bought a truck that needs an engine rebuild. If it's good, put a new set of Motorcraft plugs in it. Before putting the coils back on, I'd change the boots and springs, it's possible you may need one or more new coils, use Motorcraft, Denso, or Delphi. Make sure you put some dielectric grease in the boots. Put some Techron in the gas to clean the injectors. Check for vacuum leaks.
Check the OBD2 with a code reader or scan tool for any codes.

What is the 8th character in your VIN?NEGATIVE again. The only F-series Triton engines that have VCT are the 4.6 3 valve (2009 and 2010 only) and 5.4 3 valve (2004-2010). The 6.8 V10 does not, even the 3 valve.
If it's shaking at idle, it may need new spark plugs and/or coils or it may have dirty fuel injectors. How many miles on it and do you have any maintenance history?
