When To Replace The Spark Plug

Many drivers believe that when their car has trouble starting, it is a problem with the battery. Although this is a positive situation, it is not the only possibility. Old or faulty spark plugs may be the culprit! After all, these small spark plugs still have a lot of work to do. Understand why this is important to keep this part of your car in good working order and when to replace the spark plug by observing these bad spark plug symptoms.

It is a good idea to replace the spark plug, when...

1. Your inspection engine light is on.

Worn spark plugs or spark plug wires will trigger the check engine light. In today's cars, if the plug begins to fail, the most obvious event should be that the light to check the engine starts to light up or even flicker.

This may cause your engine to turn off and your check engine light to pop up. Flashing engine lights could mean a potentially catastrophic fire is occurring.

In general, replacing spark plugs as part of preventive maintenance is best according to the manufacturer's specifications. This can help you save expensive maintenance costs because driving with a spark plug on fire will put unnecessary stress on your car's catalytic converter (the engine's exhaust gas purifier).

Symptoms of spark plug failure include idling speed, uneven power during acceleration, and increased exhaust emissions.

Please note that checking engine lights may be caused by many potential things, not just spark plug problems.

2. Your car will not start.

Your spark plug has one of the most important jobs in your vehicle, which is the power engine that provides sparks! Old, worn spark plugs are difficult to produce sparks that really power your engine. If your car stalls and you try to open it, there may be a problem with the spark plug or a damaged spark plug wire. If your car can't start at all, the battery is most likely to be the culprit.

3. You are filling up the gas tank more often.

If your spark plug is almost finished, they will use your gas mileage to vent. Worn spark plugs will increase the fuel consumption of your car because they cannot effectively burn the fuel entering the engine, which means you will spend more money on refueling.

4. The engine is roughly idling (you can hear it!)

Normally (hopefully!) your engine may whine like a kitten, but turn your music down and listen to it. If you notice the engine rattling, banging, or crashing, it may be a spark plug problem.

5. Your car is not accelerating fast.

You may be familiar with how your car is handled and driven. If you notice that your car is not as responsive as usual, especially when you are trying to accelerate, this can be traced to a worn spark plug. Maybe it's time to replace them-no one likes to drive a slow, gas-hungry car.

6. According to the manufacturer's instructions, it's the time!

In any car maintenance matters, it is best to follow the maintenance interval recommended by the spark plug manufacturer. Check the recommended repair schedule for your vehicle to see when to replace the spark plugs.

Fortunately, the spark plug does not wear out quickly. You can usually use them for 80,000 miles before needing to be replaced. But if you notice any of these symptoms, it's time for your spark plug to check the engine adjustment.
