Turn off the ignition.
Remove the spark plug connectors by pulling on the connector, not the wire.
Squeeze the two tabs on each high-tension wire connector and pull the wire off the ignition coil.
Measure the resistance of all four high-voltage wires between the plugs at both ends of the wire. The resistance values should be between 5 kOhm and 30 kOhm.
If the resistance is too high, clean the wire connections and repeat the test, replacing the wire if necessary.
Bend the high-voltage wires in the area of the plugs and check for cracks. Replace the wire if necessary.
Place the high-voltage wire onto the ignition coil, making sure that the fastening tabs snap into place.
Note: The high-voltage wire bushings on the ignition coil are marked with numbers from 1 to 4. The wires must be installed in the correct order: 1-3-4-2 (1.3L engine: 1-2-4-3). The first cylinder is located next to the engine poly V-belt.
