Spark Plug Cable Test

  1. Disconnect, one at a time, each of the spark plug cables while the engine is idling to check whether the engine's running performance changes or not.
    CAUTION: Wear rubber gloves while doing so.
  2. If the engine performance does not change, check the resistance of the spark plug cable, and check the spark plug itself.
