Can You Drive Your Car With Defective Spark Plugs?

Can You Drive Your Car With Defective Spark Plugs?


You can’t drive your car with defective spark plugs. It’s as simple as that. If your spark plugs aren’t working, your car isn’t going to run. This post will clarify why it’s so necessary for your car to have functioning spark plugs and what could happen if they’re not working properly. We’ll also go over some of the symptoms you might experience if your spark plugs are defective.


Replace Spark Plugs at Regular Intervals

Spark plugs are a vital element of your car’s engine. They create the spark that ignites the air/fuel mixture in the cylinders, which powers the engine. If your spark plugs aren’t working properly, your engine won’t be able to run. It’s important to replace your spark plugs at regular intervals. Depending on your car and how often you drive, this could be every 30,000 miles. Changing your spark plugs is a somewhat uncomplicated and inexpensive task that shouldn’t be ignored.


If you don’t replace your spark plugs when they need to be replaced, you could end up causing serious damage to your engine. In extreme cases, you could even destroy your engine completely. It’s just not worth the risk. So if you’re due for a spark plug change, be sure to get it done as soon as possible.


Skipping Spark Plug Change At Recommended Intervals

Your Car Won’t Start Easily

If you try to start your car with defective spark plugs, it’s not easy. The engine will work harder to turn over, and it may even take a few extra tries before it finally starts up. In the cold weather, this can be especially frustrating. You don’t want to be stuck outside in the cold, trying to get your car to start.


It’s Also Harder on Your Battery


Starting your car with defective spark plugs is also harder on your battery. Every time you turn the key, the starter has to work a little harder. Over time, this can shorten the lifespan of your battery and lead to costly repairs.


Decrease in Fuel Economy


One of the cues that your spark plugs may be wearing out is a decrease in fuel economy. Your car’s engine works harder to compensate for the defective spark plugs, using more fuel than usual. If you notice that you have to fill up your gas tank more often than usual, it is time to get your spark plugs checked out. Decreased fuel economy is not something to be ignored, as it can cost you a lot of money in the long run.


Your Car Will Misfire


If you have a flawed spark plug, your car will misfire. The engine will run rough, and the car will shake. You may also witness a failure in power and fuel efficiency. In extreme cases, the engine may stall or fail to start. Driving with a misfiring engine is uncomfortable, but it’s also dangerous. A misfire can cause the engine to overheat, leading to engine damage.


In short, it’s not worth the risk to drive with defective spark plugs. If your car has any of these symptoms, it’s time for a tune-up. Please don’t wait until it’s too late!
