what Bear says, if you can log most definitely log -if you can. If you can pin it down to a single cylinder, I'd troubleshoot both the plug and the coil at the same time by swapping the coil with a cylinder that doesn't misfire, and the plug to a different "good" cylinder. For instance, if 3 is misfiring, swap the coil to 4 and the plug with 2, and then run again and see if the misfire follows the plug or the coil. That way you can tell in one step if it's one of them.

If it's not those...dunno. injectors?
