You will probably have no visual, as the spark is delivered at the bottom of the port at the plug. From a shadetree standpoint, if it is continuously misfiring, you could try and disconnect each coil, 1 at a time. Is the check engine light on, it should be. A diagnostic test may point to a single cylinder by code, or in misfire data.
