Spark Plugs Need to Be Replaced Periodically

Spark Plugs Need to Be Replaced Periodically

That little engine part called the spark plug performs a huge job in delivering a vehicle's power, performance, dependability and fuel efficiency and, according to the non-profit Car Care Council, should be replaced periodically.

"Spark plugs are one of the hardest working parts of a vehicle. A spark plug can fire 400 times per minute per cylinder or 1,600 times a minute on a four-cylinder engine," said Rich White, executive director, Car Care Council. "Many car owners delay spark plug repair on their vehicles, even after they have failed. This is a mistake since fouled, damaged or worn out spark plugs can lead to engine damage, reduced fuel efficiency and poor performance like misfiring, hard starting and sluggish acceleration."

If you spot any of the following symptoms, the Car Care Council recommends having your vehicle checked to prevent more costly problems from developing.

  • Rattling, pinging or knocking noises. When spark plugs begin to misfire, you may notice unusual noises from the force of the pistons and combustion not working properly. Pistons travel at high velocities; if the spark plug fires at the wrong time, this could lead to constant rattling, pinging or knocking sounds.
  • Hard vehicle start. If your car is having trouble starting or just feels disjointed and jerky, your spark plugs may not be working right. This can lead to misfires and erratic performance.
  • Reduced performance. Spark plugs fire when you accelerate and change gears. If the spark that the plug generates isn't functioning at 100 percent, your vehicle performance will be poor, and you'll experience a sluggish and fuel-wasting drive.
  • Poor fuel economy. Lots of things can lead to poor fuel economy. In the case of old spark plugs, fuel is wasted because your vehicle fails to receive the proper, heat-generating spark at the right time.

The Car Care Council recommends that consumers consult their owner's manual for the vehicle manufacturer's recommended spark plug replacement intervals. The council also recommends replacing all of the plugs at the same time and with the same type of spark plug that the vehicle was originally equipped.

"Replacing spark plugs is a relatively inexpensive maintenance task and can be performed by a do-it-yourselfer or by a professional technician at any auto repair shop," said White.

What Our Customers Are Saying

reviewiconI cannot recommend this gem of a business more highly!
Newtown, CT

Wow. I don't often think about the places/people who fix my car, but Newtown Car Care Center deserves special recognition. Just walking in the door was an experience; their waiting area is so cozy that I felt like I was in my living room, rather than an auto repair shop. And the folks who work there treated me more like visiting royalty than a customer. They could not have been nicer or more friendly. Johnny took care of me immediately and, thereafter, refused to take even a token gratuity from me for his trouble (turned out that I didn't need work after all). I only wish my car HAD needed repair ... that way, I could have claimed that I had contributed to their continuing success. I cannot recommend this gem of a business more highly! AAA+++

reviewiconOdometer Issue
Electronic Services, near Newtown, CT

We had trouble getting the odometer reading, which of course is required. Johnny and the customer service people were great. The odometer light finally went on enough to read and we passed! Thank you again, Johnny, for all your help.

Brought my car in for emissions inspection , it failed because I had just replaced the battery. John koshel explained why it failed and what I needed to do to pass. I did what he told me and returned for a retest which I passed. Thank you so much John for your help and caring.

I made an appointment for today's date in order to get my rear brake pads checked out after having a good experience with this company while getting emissions done. The staff along with the mechanics are fantastic here. Truly honest and willing to help. It turns out I just need some tires. The set of four came out to be a very reasonable price. I will continue to do business with this company in the future. I like to learn as much I can fumbling around with my car, however I would rather be safe with those who are knowledgeable doing advanced work on my car. Thank you.
