Check with your infrared gun at the exhaust ports, the cooler ports would be the first ones I would check. You can also crack one of the injector lines at the injector, and see if the miss gets worse or stays the same. If it stays the same that is the cylinder you have the miss in. it could be anything from a weak injector to low cylinder compression.
Good luck
