Spark plugs are a critical component to your vehicle’s internal combustion engine. Without a spark, your fuel couldn’t ignite in the combustion chamber. When running smoothly, spark plugs will burn fuel efficiently. However, faulty, bad, failing, or misfiring spark plugs can be the result of many different causes. Let’s unpack a few of these potential damaging causes and symptoms to look for:
Slow Acceleration
Similar to your vehicle’s air filters and oil, your spark plugs require routine maintenance. Every vehicle requires a specific type of spark plug made up of unique materials. Sometimes these materials can simply wear out, reducing the effectiveness of your spark plugs, leading to symptoms such as slow acceleration. If you start to notice your car running sluggishly, and it’s not accelerating as quickly as it used to, don’t just brush these observations off. This is a symptom that can indicate failing spark plugs (or other potential issues).
Poor Fuel Economy
Another common symptom that can allude to failing spark plugs is a decrease in your car’s fuel economy. What causes this decrease? Often, this is because the gap between the spark plug electrodes is either too far apart or too close, or your spark plug might just be worn out. If you notice your car’s fuel economy decreasing, or you are experiencing higher fuel consumption, have a mechanic examine your spark plugs and adjust the gap before possibly having to replace them entirely.
Engine Misfires
If your engine misfires, it’s typically because of an issue with the ignition system. However, sometimes this issue can be traced back to the spark plugs. If the wire or tip of the spark plug has been damaged, this can lead to ultimate spark plug failure. If you notice your vehicle making sputtering sounds or intermittent stumbling from the engine, have this checked as soon as possible.
Regardless of the cause, it is inevitable that your spark plugs will eventually wear out. That’s why regular maintenance on your spark plugs is necessary. Stay observant of how your car is acting and reacting to things, and remember to look for the common symptoms associated with spark plug failure!
