A spark plug is composed of materials that work together to produce a spark hot enough to ignite the air-fuel mixture. However, sometimes the issue is as simple as a worn-out spark plug. Today's modern engines have multiple sensors that tell the onboard computer and ignition system when to send electric pulses to fire the spark plug, so the issue may be with a faulty sensor. The most common cause of poor acceleration in most vehicles is a problem in the ignition system. Listed below are 6 common symptoms of worn-out spark plugs or spark plugs that have fouled and need to be replaced by an ASE certified mechanic as soon as possible. Regardless of any warranties or claims made by a vehicle manufacturer, there remain situations where a spark plug wears out or shows signs of failing. However, some newer cars, trucks, and SUVs have advanced ignition systems that ostensibly make spark plug replacement unnecessary. Most vehicles sold in the United States require their spark plugs to be replaced every 30,000 to 50,000 miles. Spark plugs are similar to motor oil, fuel filters, and air filters in that they require routine service and maintenance to keep your engine running strong. Good spark plugs will burn fuel efficiently, while bad or failing spark plugs can cause the motor not to start at all. Each vehicle requires a particular type of spark plug made from specific materials and with a designated spark plug gap set by a mechanic during installation. Spark plugs are designed to transmit an electrical signal sent from the ignition coil at a predetermined time to create a spark that ignites the air-fuel mixture inside the combustion chamber. Spark plugs have been a critical component of the internal combustion engine for years. Without a spark, there would be no way for fuel to ignite in the combustion chamber.
