Do you have good spark from ignition coil? Start there and if thats ok check for spark at spark plugs. As you asked the distributor cap gets oxidation buid up on points and rotor. This will cause misfires over time due to the spark traveling to a path of less resistance.
i will check the ignition coil first., is that usually gets bad over the time inside the distributor? thanks
