In order to ensure that your vehicle remains operational at all times, you need to invest time and effort into routine maintenance. Being able to recognize when a part of your vehicle's mechanical system is malfunctioning will help you know when to replace the faulty part in order to preserve the safety and performance of your car.

Here are three signs you should be watching for when trying to determine if you need to install new spark plugs on your car in the future.

1. Pay attention to your engine's idle.

One of the most important things you can do when trying to determine if your vehicle's spark plugs are in good condition is to pay attention to your engine's idle. If your vehicle is in good mechanical condition, then the engine should run smoothly when your car is not in gear.

If you notice that your vehicle starts to run a lot rougher than usual, this could be a sign that the spark plugs are misfiring. Have an experienced mechanic replace your spark plugs to restore a smooth idle in the future.

2. Monitor how quickly your car starts.

Spark plugs provide the initial spark required to start your vehicle's combustion engine. If the spark plugs on your car are starting to go bad, you might notice that you have difficulty starting your car.

When your engine takes a few tries to turn over, it's time to have your spark plugs checked by a mechanic. Slow starts are an early warning sign of faulty spark plugs. If you don't have the spark plugs replaced you may find yourself unable to start your vehicle, leaving you stranded. 

3. Check your gas mileage.

Fuel economy can be an indicator of the health of your car's spark plugs. If you feel like you are making more frequent trips to the gas station, deteriorating spark plugs could be to blame.

As spark plugs begin to malfunction, they can require more fuel in order to begin the combustion process within your engine. Any changes in your car's gas mileage should be checked out by an experienced mechanic so that faulty spark plugs don't compromise the performance of your vehicle in the future.

Knowing when it is time to have your car's spark plugs replaced is important when it comes to ensuring your vehicle performs properly. Pay attention to your engine when your vehicle is idling, monitor how long it takes to start your car and check your gas mileage regularly so that you can replace faulty spark plugs quickly.
