There is a cover with 2 screws in each,on each side of engine, little tight in there,under hoses and power steering reservoir. after removing covers, each plug has a coil, unhook each and pull up and out, they are about 6 in. long. use plug wreches with u joints to get down into shafts where plugs are. remove and replace plugs, reinsert coils, plug them in, replace covers, TEST engine BEFORE putting all other stuff back on. If good, finish up, if misses, check coils and connections and repeat. It is a pain in the a**.

Replace the coil pack once more. I went through 2 new ones on my f150 on one cylinder. One worked, the other didn't (both new off the shelf). Condensation build up in the boot caused mine to misfire. Anytime you replace a coil pack, squirt a little silicone grease inside. This will prevent condensation from hitting your plug. Fords are notorius for this problem, especially if you live in a humid area. Also, make sure and clear the codes after you make the repair.
