You need an ohm meter to test the resistance. Connect the probes between the 2 ends of the plug wires.
Check connections for looseness or oxidation. If there are oxidation, it means the concerned plug wire or its circuit has faults.
Check distributor cap and rotor for cracks and the ohm meter can be used to test the continuity of the rotor and distributor cap terminals.
Look out for signs of sparkings
