I will go with an off the wall but it does happen sometimes. One rocker has come loose. It only takes removing the valve cover to check. I have only seen this a few times. Depending if it is an intake or exhaust valve that is not opening results in were the misfire takes place. Sometimes times the miss is just off idle and sometimes it is under full boost. It is the reason that under diagnosis for a random misfire in WIS it has you pull the valve cover and check the rockers. Ofcourse if you have driven close to 50k miles since you replaced the plugs they could be the issue. Good Luck, Bernie
