Ignition System Issues: A Spark of Trouble

Your car's ignition system is a complex network of components that work together to ignite the fuel-air mixture in your engine's cylinders. This process, known as combustion, generates the power that propels your vehicle. Key components of the ignition system include the spark plugs, ignition coils, ignition control module (ICM), and spark plug wires.

Don't let ignition system issues slow you down. Schedule a comprehensive inspection at your local LONE TREE AutoNation service center. Our expert technicians will diagnose and repair any problems, ensuring your car's optimal performance and reliability.

Common Ignition System Issues

  • Faulty Spark Plugs: Worn or damaged spark plugs can cause misfires, reduced engine performance, and increased fuel consumption.
  • Damaged Ignition Coils: These components supply the high voltage needed to ignite the fuel-air mixture. A faulty coil can lead to misfires and engine hesitation.
  • Malfunctioning Ignition Control Module (ICM): The ICM controls the timing and duration of the spark, ensuring optimal engine performance. A defective ICM can cause various ignition problems.
  • Worn or Damaged Spark Plug Wires: These wires transmit high voltage to the spark plugs. Damaged wires can cause misfires and poor engine performance.

    Warning Signs of Ignition System Problems

    • Difficulty Starting: A weak or failing ignition system can make it hard to start your car.
    • Misfiring Engine: Misfires can cause the engine to run rough, hesitate, or stall.
    • Reduced Engine Performance: A weak spark can lead to decreased engine power and acceleration.
    • Increased Fuel Consumption: Inefficient combustion due to ignition problems can increase fuel consumption.
    • Check Engine Light: A malfunctioning ignition system can trigger the check engine light on your dashboard.

      Ignoring Ignition Issues can be A Risky Gamble

      Ignoring ignition system problems can lead to more serious issues, including:

      • Engine Damage: Severe misfires can damage engine components, such as the catalytic converter.
      • Increased Emissions: A malfunctioning ignition system can lead to increased emissions, contributing to air pollution.
      • Reduced Vehicle Lifespan: Continued neglect of ignition problems can shorten your vehicle's overall lifespan.

      To avoid these potential problems, it's important to address any signs of ignition system issues promptly. Schedule a professional diagnosis and repair at your local AutoNation dealership to ensure your vehicle's continued reliability and performance.
