5.4L 2V Spark Plug Torque Specs?
Hello. I just bought my first truck ever a week ago (2001 F150 2WD). I've learned a great deal since then by just browsing this site. 
My truck has 95k on it and a slight misfire at partial throttle in overdrive which I attribute to a weak coil or two from reading the posts here. No problem, I just picked up 8 new plugs and COPs and will replace it all when I have a free Saturday (I'll follow Otto's How-To thread on this which is excellent).
My question regards plug torque. I've read a number of posts here saying that the new torque specs call for 28-32 ft.lbs. dry. However, AllDataDIY.com says that it should be 13 ft.lbs. (no mention of whether to use anti-seize or not).
AllDataDIY.com is pretty thorough with the service bulletins but I did not see anything regarding plug torque. Does the 28-32 ft.lbs. spec come from Ford through some service bulletin that I am not seeing?
Since screwing this up could mean big $$$ in a head repair, I want to make sure I am doing this right. Thanks.

Happy to know that you did fix it and information on the threads really helped but as far as such a technical problems are considered i always prefer to get information as well as help from a technician as they do have proper info about vehicles and avoid the hassles that we may face doing it our selves.

Plugs should be installed dry. No lubricants/anti-seize required.
Unless you have an inch-pound torque wrench just turn them in until they seat, then turn a touch more. That will be sufficient to seat them without over-torquing.
