Ignition System Inspection

■ Spark Plug Cable & Ignition Coil Inspection 

1. Visually/physically inspect the spark plug cable and ignition coil related to the misfiring cylinder (s) for the following conditions
   • Damage, cracks, carbon and flashover
   • Poor connection or damaged harness
   • Connected to the incorrect cylinders at the ignition coil and spark plug
2. Measure the resistance of the spark plug cable related to the misfiring cylinder (s)

   Specification:  5.6k/m ±20%

3. Measure the resistance of the primary and secondary ignition coil related to the misfiring cylinder (s)

   Specification: 

   Primary Ignition Coil Resistance: 0.56~0.68 at 20°C(68°F)

   Secondary Ignition Coil Resistance: 6~8k at 20°C(68°F)

4. Was a problem found in any of the above areas?

   YES 

   • Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

   NO 

   • Go to next step as below.

■ Spark Plug Inspection 

1. Visually/physically inspect the spark plug related to the misfiring cylinder (s) for the following conditions
