Being attuned to your Subaru’s sounds and movements will keep your vehicle performing as you expect for years to come, and one of the critical components demanding your attention is the ignition coil. This small device is the heart of your Subaru’s ignition system, supplying power to the spark plugs. When you have a faulty ignition coil, there will be some signs that you need to head to your San Jose Subaru dealer.
Misfires
Think of the ignition coil as the conductor of an orchestra, ensuring each spark plug fires in harmony. A faltering coil can disrupt this symphony, leading to irregular or absent spark plug firing. This disharmony manifests as stuttering, shaking, or a lack of power, especially during acceleration. Often, this is a result of wear and tear or exposure to excessive heat, affecting the ignition coil’s integrity.
Poor Fuel Economy
When the ignition coil is not performing at its peak, the spark plugs may not receive the optimal voltage. This can lead to incomplete combustion in the engine, causing your Subaru to consume more fuel than necessary. This increased thirst is not just a blow to your wallet, but an indication that your ignition coil needs attention.
Warning Lights
The modern-day Subaru is equipped with a check engine light, and when the ignition coil is compromised, this will light up as a warning. However, this light can indicate a myriad of other possible issues, too. A professional diagnosis is required to confirm if it’s the ignition coil that is the source of the problem, as it might also be due to electrical shorts or other issues in the engine.
Unusual Smells
An unexpected smell of gasoline from your Subaru’s exhaust can be caused by an ignition coil unable to supply sufficient power to the spark plugs. This means the fuel may not be burning efficiently, leaving unburned fuel behind. This unburned fuel escapes through the exhaust, releasing a potent aroma of gas.
