Misfiring Need help!

[nixnix]

I need help on figuring out what is causing my GN to misfire under full throttle. It is fine just crusing and up to 3/4 throttle. When I give it full throttle it will start to mis fire but it doesn't do all the time.
Could it be the spark plugs or the wires?
thanks.

Coil could be going bad.

plugs, wires, coil pack
