Losing Your Spark (Spark Plug Replacement)

March 30, 2025

When's the last time you thought about spark plugs? You probably don't remember.  That's because spark plugs usually last a long time and don't need much attention.  But they don't last forever, and when they start going bad, they'll send you a few clues.

  • Vehicle is hard to start. 
  • Fuel economy is going down
  • Acceleration isn't what it used to be
  • Engine runs roughly
  • Check Engine light is on

There are many things that can cause those symptoms, so it's wise to head on over to your vehicle repair facility to have them look over your vehicle.  But the problem could be your spark plugs. They do wear out, not producing a strong enough spark to ignite your fuel the way they're designed to.  A closely related problem is failing spark plug wires, and a technician will test for both possibilities… and more. 

Your vehicle's manufacturer recommends changing wires and/or plugs at certain intervals.  Spark plugs are made out of different materials and some last far longer than others.  Ask your service advisor to let you know when yours should be changed.  Badly misfiring plugs can cause expensive damage to a vehicle's catalytic converter, so it's best to take care of them before that happens.  Replacing your spark plugs and/or wires is money well spent to have your vehicle running smoothly, dependably and efficiently.
