The numbers below refer to the step numbers in the diagnostic procedures.

1. 5
   
   If the Misfire Current Counters are incrementing, but the engine is NOT misfiring, this indicates a mechanical condition. For example, an accessory drive belt could cause this condition.

   The spark should be consistent when you test the spark at the spark plug wires. The presence of few sparks then nothing indicates no spark.
