2000 Ford Excursion V10 Two Wheel Drive Automatic 120 miles

I have a 2000 Ford Excursion, My check engine light came on"when running cut out and will stull if one don't keep there foot on the gas. When starting truck has to run for 10 to 15 min before truck idels on it's own. So I hooked it up to the computer and it told me the #6 coil and Plug was bad so I replaced both. Ran the same way so I replaced 8 out of the 10 plugs and it is still running the same. The computer is still telling me the same thing that the #6 needs replaced. What would make the truck run like this?

WHen you replaced the coil, was there a new rubber boot for the plug?
