distributor cap contacts keep fouling. clean contact pins or replace cap and engine runs fine for 500 to600 miles and fouls again and misfires real bad. changed coil , no resolve.
When was the last time you changed ignition wires? They degrade over time. http://www.ehow.com/how_7592234_test-ignition-wires.html
changed wires and plugs,cap and rotor 6 months ago. coil yesterday. looking into the possibility of a malfunctioning icm (have not found out how to test it yet) or an ecm problem. The fouling is a hard white crusting that has to be sanded off.
