4 Signs of a Faulty Ignition Coil

4 signs of a faulty ignition coil near santa clara, ca

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.

Get Your Ignition Coil Repaired by Your Subaru Dealer

Listening to and interpreting the signs of a dying ignition coil is a critical skill for every Subaru owner. When your car's engine misfires, fuel economy dwindles, warning lights illuminate, or a gasoline aroma envelops your vehicle, it is time to take action.

Our adept technicians are trained on all things Subaru, including ignition coil repair, and we are dedicated to restoring the harmony your Subaru deserves through our combination of experience, training, and use of OEM parts that always fit and perform like the original.

How to Maintain Your Subaru's Battery for Optimal Performance

Car batteries tend to be pretty low maintenance, but there are still some things you should do to keep yours in the best condition possible. Visiting your San Jose Subaru dealer for car battery service regularly is essential, and there are also things you can do at home. more Visit Your Bay Area Subaru Dealer for Car Battery Service The key to keeping your battery working well is getting regular battery service, so visit your Bay Area dealer approximately every six months. The mechanics at the dealership can perform several essential checks to see how your battery is doing. For example, they need to check your battery for acid stratification. If the battery is stratified, then it can't charge above 80 percent. The mechanics at your local dealer also need to do a battery load test to check whether or not the battery can charge up properly. If your battery can't charge properly, then the mechanics will run an engine diagnostic to figure out what's causing the problem. Once they know what the problem is, they can work on fixing it. Keep the Battery in Place The vibrations caused by driving can sometimes damage your battery's internal connection. You can minimize the effects of vibration by using a hold-down system to stop the battery from shaking while your car is running. It's important to check this hold-down often to make sure it's still keeping your battery secure. Take Long Trips Aim to drive at least 10 miles every time you drive. Understandably, this isn't always possible, but limiting trips that are shorter than 10 miles can help your battery work better for longer. Short trips don't give your battery enough time to fully recharge, and that has a negative impact on your battery's health. Don't Let the Battery Get Too Hot or Cold Extreme weather can wreak havoc on your battery. When it's very hot outside, aim to park in the shade, such as under a tree. A car cover may also be helpful if there's no shade around that you could park in. When it's particularly cold outside, aim to park in a garage. A battery blanket can also help keep your battery warm when it's freezing outside. Drive Regularly Drive for at least 30 minutes every week so your battery has enough time to fully charge up. If you don't drive, then the battery will only last a month or two before it dies. If you'll be away for more than a month, then it'd be wise to have a friend drive your car for 30 minutes every week so you don't have to jumpstart the battery when you get home. Stop by Stevens Creek Subaru in Santa Clara, CA for battery service today. We'll perform a battery health check and replace your battery when needed.
