When Do I Change Spark Plugs? 

Effective spark plugs are critical for reliable engine performance. When you start your vehicle, the spark plugs work to move the high voltage current from the ignition coil to ignite the combustion chamber. If that process is impeded by worn-out spark plugs, you may notice the following signs on your Bessemer commute:

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