Spark Plug Replacements in Batavia, IL

Spark Plug Function And Failure

Internal combustion engines work using small, controlled explosions to create power. High voltage from a coil passes through the spark plug, jumping the gap between the main body of the plug and the tip to ignite an air-fuel mixture. Spark plugs generally last a long time, firing time and after time without issue. However, once they become worn—often noticeable when the tip begins to wear away—they become less effective or even nonfunctional and must be replaced. When you bring your vehicle to Reliable Auto Repair for a tune-up, we’ll inspect the plugs, cleaning or replacing them as needed. However, some signs of failing spark plugs should prompt you to bring your vehicle to us when you notice them. One possible symptom is difficulty starting your car. While this can also point to other issues, such as a bad battery or frayed wiring, it could be aging spark plugs. You may also recognize that your transportation is beginning to use a lot more fuel than normal. That’s because improper combustion leaves a lot of fuel unburned and, therefore, wasted. Furthermore, your car may develop a rough idle. This will cause a jerking feeling or a ragged sound when you’re sitting still with the engine running. Misfiring can occur, too. That’s similar, but it occurs when you’re moving. You can feel the engine cutting out due to insufficient power supply. Conversely, the engine may surge when the next firing does occur. Finally, you may feel there’s not enough power when you accelerate, which can be dangerous, particularly in traffic. Left unaddressed, bad spark plugs can lead to more significant damage that’s costly to repair.
