Sonata GL V6-2.5L (1999)
Ignition Cable: Testing and Inspection
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.
2. If the engine performance does not change, check the resistance of the spark plug, and check the spark plug itself.
3. Check the cap and outer shell for cracks.
4. Measure the resistance.
<For 2.5 Liter Engine>
NOTE: Resistance should not be higher than 10,000 Ohm-per foot of cable. IF resistance is higher, replace the cable.
INSPECTION AND CLEANING
1. Disconnect the spark plug cable from the spark plug.
NOTE: Pull on the spark plug cable boot when removing the spark plug cable, not the cable, as it may be damaged.
2. Using spark plug wrench, remove all of the spark plugs from the cylinder head.
NOTE: Take care not to allow contaminants to enter through the spark plug holes.
