Working hand-in-hand with the spark plug, the wires that connect them are equally important to the efficient operation of your vehicle. Worn out spark plug wires can ground the electricity to places where it shouldn't be going.
Some signs that your spark plug wires need replacement are:
- Random mis-fires
- Idle fluctuation
- Loss of power
- Irregular vehicle performance
- Poor mileage
Spark plug wires should be checked during regular scheduled maintenance.
