Why Spark Plugs Are Essential for Your Engine
Spark plugs are a critical component of your car’s ignition system. They create the spark that ignites the air-fuel mixture in your engine, allowing it to run smoothly. When spark plugs wear out, they can cause a range of performance issues that impact your vehicle’s efficiency and drivability. Knowing how to recognize the signs of bad spark plugs can help you avoid costly repairs and keep your car running in top condition. If you're unsure about your spark plugs, visit Marble Falls Auto Center for a professional inspection.
Common Signs Your Car Needs New Spark Plugs
1. Difficulty Starting the Engine
Worn-out spark plugs can make it harder for your engine to turn over. If you notice your car struggling to start or experiencing frequent misfires, your spark plugs might be failing.
2. Engine Misfires or Rough Idling
A misfiring engine can cause noticeable vibrations, especially when idling. If your car shakes excessively at a stoplight or struggles to maintain a steady idle, replacing the spark plugs might resolve the issue.
3. Decreased Fuel Efficiency
Bad spark plugs can lead to inefficient combustion, causing your engine to use more fuel than necessary. If you find yourself filling up the gas tank more often than usual, your spark plugs could be the culprit.
4. Lack of Acceleration and Power
If your vehicle feels sluggish or doesn’t respond as quickly when you press the gas pedal, worn spark plugs may be to blame. Replacing them can restore your car’s performance and responsiveness.
5. Check Engine Light Is On
Many modern vehicles have sensors that detect misfires caused by faulty spark plugs. If your check engine light comes on, it’s a good idea to have a professional diagnose the issue at Marble Falls Auto Center.
How Often Should You Replace Spark Plugs?
The lifespan of spark plugs varies depending on the type of plug and your driving conditions. In general:
Copper spark plugs last about 20,000 to 30,000 miles.
Platinum or iridium spark plugs can last up to 100,000 miles.
High-performance engines may require more frequent replacements.
To ensure your engine stays in optimal condition, check your owner’s manual or have a professional mechanic inspect your spark plugs during routine maintenance.
Why You Shouldn’t Ignore Bad Spark Plugs
Driving with worn-out spark plugs can lead to:
Increased emissions
