While there are a few possible reasons why your car’s engine might be knocking, bad spark plugs are often the culprit! There are six spark plugs in a V6 Dodge Durango—one for each engine cylinder.
In addition to strange engine sounds, here are a few other signs of faulty spark plugs:
  • Difficulty starting your car
  • Vibrations or rumbling sounds while idling
  • Slow or jerky acceleration
  • Poor fuel efficiency
