I started this thread back around November when I took my 07 F150 to my friend for a tuneup. I bought 8 new Motorcraft coils and plugs from Amazon and he provided the labor.Truck has been great ,till last Friday.The wife and I were going to dinner and the damn thing started missing and has been since.I've put less than 3000 miles on the truck since the new plugs and coils were installed.Really frustrated at this point,counting parts and labor,that tuneup was right at $1000.00,now it's got to go back in the shop.Very pisspoor design on Ford Motor Company's part if you ask me.The idiot of an engineer that designed this should have been put before a firing squad,or at least hung by his thumbs.

its too expensive for a tune up. when i did my tune up i chekedmy coils (ohms) and they were the same, spak plugs holes very clean to dont let compression escape, and everything was ok, i guess one of your coils are bad, they used to fail even if are new, post if you know the problem with your truck.
