Do Your Spark Plugs Need Repair or Replacement?


Having good spark plugs in your vehicle helps your engine be more reliable because they are what provide the spark that helps ignite the mixture of air and fuel for it to run. Here are some signs that those spark plugs are in need of repair or replacement.

Rough Idling

Pay attention to how your car behaves when the vehicle has started and you are at a complete standstill. If your vehicle's RPM meter is going up and down, this is a sign that your engine is misfiring and could be due to bad spark plugs. A tiny amount of movement when idling is normal, but there should not be significant changes in RPMs while idling.

Engine Misfiring

There are many signs of engine misfiring that could be due to bad spark plugs. Look out for symptoms like having an excessive amount of smoke coming out of your exhaust, weird odors or sounds coming from your vehicle, or moments where it feels like your vehicle is losing power. While these are not always due to the spark plugs going bad, it is a reason to have your vehicle inspected for a potential problem since changing the spark plugs can be a simple fix.

Increased Fuel Consumption

Have you noticed that your vehicle is now consuming more fuel, even though you haven't changed your driving style? This is a big reason to be concerned. Confirm your suspicions by tracking how many miles you get per gallon on a full tank of gas, and comparing that to what it was in the past. Some vehicles even track your average miles per gallon, and you can easily reset that meter and see what your vehicle now gets in comparison.

Slow Acceleration

You know how your vehicle should feel when you accelerate, including how quickly it gets up to your desired speed when starting from a standstill or going onto the freeway. If the vehicle now feels like it is accelerating much slower, this is a sign that the spark plugs have gone bad. 

Unsure if your vehicle's problems are spark plug-related? Have a mechanic check out your engine and let you know what is going on under the hood. If the spark plugs are bad, consider swapping out all of the spark plugs at once, since the cost to do so is low and can prevent these problems from happening in the future.
