Was anything done prior to this occurring?
When the spark plug cable is disconnectecd with the engine running, the sparks need to find a grounding point and that is where you would see the arcing, near the distributor cap.
As to Code 4, did you test the wiring circuit for the sensor?
When the CEL is triggerred, the ECM woul go in limp mode and would not allow you to rev the engine moe than 3500 rpm.
