When Do I Change Spark Plugs?

While they may be small, spark plugs play a large role in moving the high voltage current from the ignition coil to ignite the combustion chamber so that your vehicle can start up. When spark plugs aren’t working properly in a vehicle, you may not be able to start your car. Here are some other issues that come along with having malfunctioning spark plugs:

  • Engine misfire
  • Rough idling
  • Higher than normal fuel consumption
  • Slow or no start
  • Poor acceleration
  • Rough-running engine
