The rotor arm has corroded the dizzy cap ignition points, is this a common problem or is the spark to powerful to cause this rapid erosion. Is the spark controlled by the ECU via readings from lambda sensors Or O2 sensors????etc...
certain things like mileage on the vehicle, are theses original equipment componants or recently replaced, year of vehicle may also be benifitial. Last question on your list...Spark is controled by the DME yes, but not determined by the lambda/O2 sensors (lambda/O2 sensors are for fuel).
