Many drivers assume that when their car has trouble starting, there’s a problem with the battery. While this certainly could be the case, it’s not the only possibility. Old or faulty spark plugs could be the culprit! After all, these small spark plugs have a big job to do.
If your car isn’t running as smoothly as it used to, it might be time to change your spark plugs. Over time, spark plugs can become fouled or damaged, affecting your car’s performance.
Here are 6 telltale signs that you need to change your spark plugs:
1. Your Car is Hard to Start
One of the first signs that you need to change your spark plugs is if your car is having difficulty starting. If it takes longer than usual for your car to turn over, or if it sounds like it’s struggling to start, it could be a sign that your spark plugs are worn out.
2. The Engine Misfires
Another sign that you need to change your spark plugs is if your engine starts to misfire. If you notice that your car is sputtering or stuttering when you try to accelerate, it could be a sign that the spark plugs are not firing correctly.
3. The Engine is Running Rough
If you notice that your engine is running a little rougher than usual, it might be time to change your spark plugs. A rough engine can be caused by several things, but one of the most common is a fouled or worn-out spark plug.
4. You’re Experiencing Power Loss
If your car seems to be lacking power, it could be due to spark plugs that are worn out or fouled. When spark plugs are in good condition, they create a strong spark that ignites the fuel in the engine. However, when they are worn out or fouled, the spark isn’t as strong, which can lead to a loss of power.
5. Your Fuel Economy Has Decreased
If you’ve noticed that your fuel economy has decreased, it could be due to spark plugs that are worn out or fouled. When spark plugs are in good condition, they create a strong spark that ignites the fuel in the engine. However, when they are worn out or fouled, the spark isn’t as strong, which can lead to incomplete combustion and a decrease in fuel economy.
6. It’s Been a While Since You’ve Changed Your Spark Plugs
It’s always best to follow the car manufacturer’s suggested maintenance schedule when it comes to car care. This way you can be sure you’re replacing your spark plugs at the right time.
The average lifespan of a spark plug is 80,000 miles, but they may need to be replaced sooner if you notice any of the following symptoms mentioned above.
If your car is experiencing any of the telltale signs mentioned in this article, then it is probably time for you to change your spark plugs. Of course, it is always best to consult with a professional mechanic to be sure. But, in general, if your car is idling roughly, losing power, or experiencing any kind of engine misfire, then new spark plugs may be the solution.
