5.4 V8 Coil Packs

Can someone tell me how to check coil packs. Think got one bad, cuts back in overdrive or when truck goes into a strain.

They are coil-on-plugs, not coil packs. Terminology difference and you will invoke the wrath of jbrew if you call them coil packs.

How many miles on your spark plugs, and what brand are they?
