Losing Your Spark (Spark Plug Replacement)

Posted December 17, 2024 8:39 AM

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.

What our clients are saying about us

We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!

I’ve trusted Dennis Road Automotive for many years, though it’s been a while since my last visit, mainly because they’re not open on weekends. I’ve always appreciated their straightforward service, and I still miss Riley, who brought a great personal touch to the experience. On my most recent visit, I was charged $374 for a new battery for a Lexus ES350. I’m not sure how that compares in today’s economy, but it gave me the same feeling you get when dining out these days, quality isn’t necessarily better, yet the prices seem to jump significantly. The work was completed, and the team was professional, but the cost left me wondering if the value aligns with what it used to be. I still want to support businesses that have served the community for so long, and I hope they continue to provide honest, dependable service at a price that feels fair in the current market. quotes-image
