If your vehicle is misfiring, hard to start, or struggling with poor fuel economy, the problem could lie with your ignition coil. At Advanced Auto Works in Livermore, we specialize in diagnosing and performing ignition coil replacement services to get your engine running smoothly and efficiently again. Whether you drive a Ford, Chevrolet, Jeep, or Toyota, our certified technicians are equipped to handle the job right the first time.
The ignition coil is a key component of your engine’s ignition system. Its main job is to convert the low voltage from your car’s battery into the high voltage needed to create a powerful spark at the spark plugs. This spark ignites the air-fuel mixture inside the engine cylinders and keeps your vehicle running.
Without a functioning ignition coil, the engine may:
Fail to start
Misfire under load or acceleration
Run rough or uneven
Burn more fuel than necessary
Cause your check engine light to activate
In some vehicles, each cylinder has its own ignition coil, while others use a single coil to power multiple spark plugs. Either way, ignition coil failure can severely impact engine performance and fuel efficiency.
Recognizing the symptoms of a failing ignition coil can help prevent further engine damage. Here are common warning signs to look out for:
Engine misfiring or shaking while idling or accelerating
Difficulty starting your vehicle, especially in cold weather
Decreased fuel economy or sudden drops in MPG
Loss of power under acceleration or uphill driving
Backfiring or loud popping noises from the exhaust
Check engine light illuminated, often with misfire-related codes
Unusual exhaust emissions or increased tailpipe smoke
If you're experiencing any of these issues in or around Livermore, bring your car to Advanced Auto Works for a full diagnostic. We’ll determine whether the issue is with a single coil, multiple coils, or related components like spark plugs or ignition wires.
