5 Signs that You Need a Spark Plug Replacement

Keep your car in tip-top shape by maintaining your spark plugs.

Spark plugs play an important role in your engine. Without them, your car won't be able to start or run. Because of that, you have to keep a careful eye on them and ensure they’re working properly and well-maintained.

However, anything can happen, and one of these days, you might encounter a problem with it. You should have your spark plugs checked or replaced when that time comes. But how will you know when the time to replace them has come?

No need to worry. We have it covered. This blog will tell you how to find signs you need a spark plug replacement.

Your Car Uses More Fuel Than Usual

If you notice that you need to stop at the gas station more often than usual, your spark plugs might be to blame. This happens when worn and old spark plugs make your engine work harder than before and aren't burning up fuel effectively.

The Check Engine Light is Flashing

Some people make a habit of thinking that it doesn't really matter or nothing bad is going to happen whenever their Check Engine light is flashing or is on. If you have that habit, it's best not to ignore the flashing lights. This is one of those helpful features where, if you forget to have your scheduled maintenance, it can notify you if something needs your attention. A spark plug issue might be why the lights are coming on. You should have that checked to confirm if that’s the case.

The Engine Growls Instead of Purrs

You might have heard and are familiar with the saying, 'Your engine purrs like a cat'. Well, that's pretty close. If cats are purring, it means that they are content and happy. Therefore, if your car is also purring, it's in good health and peak condition. However, there might come a time when your engine is growling like an angry lion instead of purring like a cat. If that happens, your spark plugs might be behind those angry and discontented car noises.

Starting the Car Gets Difficult

If you are having trouble starting your car, it might be a problem caused by two things. Your car battery or your spark plugs. More often than not, the battery gets blamed, but sometimes, it's the spark plug's fault. This is because the battery isn't the only one powering the start-up of your car. You might want to consider if your spark plugs are behind why your car is stalling this time.

It Reached Its Inevitable End

No matter if something has a label that says it's sturdy and long-lasting, nothing lasts forever. You might not have experienced any trouble with your spark plugs since you had them. Still, sooner or later, they will reach their inevitable end. Even though spark plugs don't wear out quickly, you must have them checked during your scheduled maintenance. You should have them replaced if you think your spark plugs are nearing their end.

Spark plugs may be just one of the little—literally—cogs that power up your vehicle. However, they play a vital role in starting and running your engine. If you notice one of the signs above on your car, it's best to have them checked and replaced immediately. This way, you can prevent any potential accidents or damages to your vehicle.
