If your car's spark plugs are bad or failing, you may notice one or more of the following symptoms. Engine misfires, poor fuel economy, the engine running rough, and the 'check engine' light being on are all signs that your spark plugs may need replacing.
The best way to prevent failing spark plugs is to perform regular maintenance and use high-quality spark plugs.
Symptoms of Bad or Failing Spark Plugs
A spark plug that is failing or has gone bad can cause an engine to misfire. The symptoms of a misfiring engine are a decrease in power, acceleration, and fuel economy. You may also notice that your engine is running rougher than usual and that the check engine light is on.
Poor Fuel Economy
Another symptom of bad spark plugs is poor fuel economy. If your spark plugs are worn out, they will not be able to ignite the fuel efficiently. This will cause your engine to run less efficiently and use more fuel.
The Engine is Running Rough
If your spark plugs are worn or damaged, they can cause your engine to run rough. You may notice your engine is shaking or vibrating more than usual. The check engine light may also come on because of spark plugs that are not firing.
How to Prevent Bad or Failing Spark Plugs
If you want to prevent failing spark plugs, the best thing you can do is keep up with regular maintenance. Therefore, change your spark plugs regularly and keep an eye on your spark plug wires to ensure they're in good condition.
Use High-Quality Spark Plugs
Using high-quality plugs from a reputable brand will help ensure that your plugs are less likely to fail and will last longer.
Bad or failing spark plugs can cause several engine performance issues. The most common cause of bad spark plugs is wear and tear, but it can also be because of a faulty ignition system or carbon deposits. If you need spark plug replacement, give Kaufman's Auto Repairs Inc. a call today.
