When Do I Change Spark Plugs?

Spark plugs play a vital role in the performance of your vehicle and should not be neglected.

The following signs are an indicator that your spark plugs aren’t functioning properly:

  • Slow or no start
  • Engine misfire
  • Engine is running rough
  • Rough idling
  • Poor acceleration
  • High fuel consumption
