Hard starting, misfires or a rough idle can point to a worn plug, but ignition and fuel parts can also be behind them, so find the cause before you replace it. With the engine off and cool, look at a removed plug for rounded electrodes, oil or carbon fouling and a cracked insulator; a shop can test the ignition side.
