Hard starting, a misfire or a rough idle can mean a plug is worn. A weak coil or a fuel problem can also make an engine misfire, so with the engine off and cool, look at a removed plug's electrode tip and insulator for wear or cracks before you buy. This listing is one plug; a V8 6.3L takes one per cylinder, eight in all.
