Have you tried to unplug injector plugs and or spark plug wires while running?
This would narrow it down to a cylinder.

If that doesn't get you anywhere, a compression test, coupled with hooking up a vacuum gauge would be a good next step. A burned valve often manifests itself as a miss at idle that becomes less noticeable once underway.
