Have you checked your battery cables. They are routed underneath the truck and exposed to a lot of wear and tear in the under carriage. If you notice any cracks or swelling in the plastic coating they need to be replaced. Check your vacuum lines running off the octopus for any cracked or loose lines. Also check your PCV valve, do this ny removing it and shaking it with your hand. If it doesn't rattle freely, replace it. Have you cleaned you MAS or your throttle body?
P.S. I found a set of cables at PEP BOYS for about half of what Ford wanted and they were the only place I could find that had a direct replacement.
