Dirty spark plug vs clean spark plug

When their cars fail to start, many drivers blame a faulty battery. While this is a possibility, they should also check their spark plugs. These parts may be small, but they play a crucial role in your vehicle’s performance. This is why it’s important to ensure that they are always working properly.

You should also know when to have a tune-up or change your spark plugs. If you need new ones, it’s also important to choose a reliable shop like Jiffy Lube. Below are some of the signs you should watch out for to know if you need to change your spark plugs.

Your Check Engine Light Is On

There are many possible reasons why your check engine light is on. To be sure, you should take your car to the nearest Jiffy Lube branch and let our technicians check your vehicle. But one of the possible reasons for the check engine light to turn on is faulty spark plugs, which can cause your engine to misfire.

If you have a misfiring engine, you can experience uneven power during acceleration, rough idling, and increased exhaust emissions. This is a serious problem that needs to be addressed right away. According to the manufacturer’s recommendations, you can replace your spark plugs and have a tune-up as a form of preventive maintenance. This can help save you from costly repairs in the future.

There’s a Problem Starting Your Car

You can’t use your car if you can’t start it. This is why their role is very crucial. They are responsible for providing the spark needed to start your engine. If they are old and worn out, they may have a hard time powering your vehicle.

If your vehicle has no power and won’t turn on, you most likely have a battery problem. But if your vehicle stalls when you attempt to start it, there’s a good chance there’s a problem with your spark plugs. If you have trouble starting your vehicle, take it to Jiffy Lube for a replacement or tune-up.

Decreased Fuel Efficiency

If you notice that you’re going to the gas station more often, faulty spark plugs can be the culprit. They are inefficient and effective in burning fuel, increasing your fuel consumption. The problem can reduce fuel economy by as much as 30%.

Your Car Is Not Accelerating Quickly

You’re probably familiar with the handling and driving of your vehicle. So if you notice that it’s not accelerating quickly, you know that there’s a problem. The possible reason is a worn spark plug. Maybe it’s time to have it replaced at Jiffy Lube.

Your Engine is Idling Roughly

Normally, a running engine sounds like a purring kitten. If your engine is making a pinging, rattling, or knocking sound, then it means your engine is idling roughly. The possible reason is worn spark plugs.
