Mike,
Sometimes you can see carbon tracks inside the cap between electrodes. If there's any question about the rotor & cap I would change them as a normal tune up step chasing a misfire/backfire. Same with your plugs. With the move to offshore manufacture by many of the "major" names there have been too many cases of bad plugs out of the box. Everyone has their favorites, but I now use NGK exclusively.
