Spark Plug Wires

TESTING



See Figure 1

At every tune-up/inspection, visually check the spark plug cables for burns cuts, or breaks in the insulation. Check the boots and the nipples on the coil or distributor, if equipped. Replace any damaged wiring.

Every 50,000 miles (80,000 km) or 60 months, the resistance of the wires should be checked with an ohmmeter. Wires with excessive resistance will cause misfiring, and may make the engine difficult to start in damp weather.

Fig. Fig. 1: Checking individual plug wire resistance with a digital ohmmeter

To check resistance, disconnect the spark plug wire from the plug and ignition coil or distributor, then use an ohmmeter to measure the resistance.

For the 2.0L DOHC engine, the resistance should measure no more than 8000 ohms maximum.

For 2.0L SOHC and 2.4L DOHC engines for 1995, the resistance should be 250-1000 ohms per inch or 3,000-12,000 ohms per foot.

For 2.0L SOHC and 2.4L DOHC engines for 1996-98, the resistance should be follows:



Cables #1 and #4: 3,500-4,900 ohms.
 
Cables #2 and #3: 2,950-4,100 ohms.
 

For the 2.5L SOHC engine for 1995, the resistance should be 250-550 ohms per inch or 3,000-6,600 ohms per foot.

For the 2.5L SOHC engine for 1996-98, the resistance should be 250-560 ohms per inch or 3,000-6,700 ohms per foot.

If resistance falls outside of specifications, the cable(s) should be replaced with new ones.

REMOVAL & INSTALLATION



As the spark plug wires must be routed and connected properly, if all of the wires must be disconnected from the spark plugs or from the ignition coil pack/distributor at the same time, be sure to tag the wires to assure proper reconnection.

When installing a new set of spark plug wires, replace the wires one at a time so there will be no mix-up. Start by replacing the longest cable first. Twist the boot of the spark plug wire 1 / 2 turn in each direction before pulling if off. Install the boot firmly over the spark plug. Route the wire exactly the same as the original. Insert the nipple firmly onto the tower on the ignition coil or distributor, if equipped. Be sure to apply silicone dielectric compound to the spark plug wire boots and tower connectors prior to installation.
