The distributor will have white deposits on each metal tap inside cap and the rotor will be worn down. Take a look under the cap try not to disconnect the spark plug wires just unhook the cap and turn it so you can look inside. That's the easy thing to do. If the cap has the deposits you need a knew cap and rotor I would get knew wires and check your spark plugs as well.
