SPARK PLUG CABLES 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.
  1. If the engine performance does not change, check the resistance of the spark plug, and check the spark plug itself.

  1. Check the cap and outer shell for cracks.

  1. Measure the resistance.

NOTE
Resistance should not be higher than 10,000OHM-per foot of cable. If resistance is higher, replace the cable.
INSTALLATION OF SPARK PLUG CABLE

Improper arrangement of spark plug cables will induce voltage between the cables, causing miss firing and developing a surging at acceleration in high-speed operation.

Therefore, be careful to arrange the spark plug cables properly as shown in the illustration.
