then i would replace whats called the hall effect sensor its that black plastic plate you see when you take dist cap off. just pull rotor and lift up the sensor.dist cap is what holds it on.also under the sensor will be a stamped sheet metal piece that looks like the top of a castle wall. make sure its not loose on the shaft.if it is then new dist will be needed
