5 Ways Your Car Is Telling You It’s Time for New Spark Plugs

Small but Mighty, Spark Plugs Are Necessary for Vehicle Health

Spark plugs are small but necessary for a healthy, running vehicle. They provide the spark needed to trigger combustion in your engine. Most spark plugs are designed to last up to 100,000 miles, but our experts recommend checking them as part of your routine maintenance services. This is the best way to avoid the time, headaches, and costly automotive repairs down the road. So, how do you know if it’s time for new spark plugs? The ASE-certified technicians at Dickerson’s Service Center specialize in auto repair and maintenance and have identified five signs it’s time for new spark plugs.

5 Signs You Need New Spark Plugs

Trouble Starting

If a spark plug can’t create a spark, the fuel going to the engine can’t be ignited. If the spark plugs don’t work, neither will your vehicle. A dirty, damaged, or worn-out spark plug may be the culprit if the battery is healthy. Drivers in Creedmoor, North Carolina, should visit our auto repair experts for a thorough inspection and dependable car repairs.


A sputtering sound, sudden loss of power, or violent shaking can indicate a misfire. Misfires can lead to poor performance, low fuel economy, and costly auto repairs. Having your spark plugs checked during routine maintenance services can help avoid this problem.

Rough Idle

While your vehicle idles, listen for any rattling, pinging, or knocking sounds. Unusual sounds like this or vibrations while idling can indicate faulty spark plugs. Following your manufacturer’s suggested factory maintenance services can help sidestep more extensive auto repairs in the future.

Lack of Acceleration

If your vehicle seems to have lost its giddy up-n-go, bad spark plugs could be to blame. However, dirty fuel injectors, a bad fuel pump, or faulty oxygen sensors can also be the guilty party. This is when you rely on the auto repair authorities at Dickerson’s Service Center to inspect your vehicle and make a proper diagnosis.

Poor Fuel Mileage

If the spark plugs aren’t igniting the fuel properly, your vehicle’s onboard computer will send more fuel to the engine to compensate. This wastes fuel and costs you money.
