5 Signs of a Faulty Ignition Coil

A faulty ignition coil can cause multiple performance issues with your vehicle. Your car could backfire, misfire, or even fail to start. When you’re having problems with your coils, you need to head to your local Cadillac dealership so you can have the faulty component replaced.

5 Signs You Need to Head Your Cadillac Dealership Because of a Faulty Ignition Coil

1. Your Check Engine Light Is On

You glance down at your dashboard and notice there’s an engine-shaped yellow/orange light illuminated on it. This is your check engine light, and it means you need to get to the dealer for an engine diagnostic ASAP. There could be something minor wrong with your engine, or you could have a more serious issue that needs immediate attention. This light can illuminate for a whole range of reasons, including a faulty coil.

2. You Have Trouble Starting Your Car

You get behind the wheel one morning and turn on the ignition, but the car doesn’t start straight away. This can be caused by many faulty components in your vehicle, including one of the coils. Because the bad coil can’t deliver a spark to your spark plugs, the engine has difficulty getting started.

3. You Have To Stop for Gas More Frequently

You look down at your dashboard and notice that the gas tank is almost empty. It seems like you just filled the tank up a little while ago, so that’s strange. As the days progress, you notice your tank is emptying faster and faster. This typically points to a problem with one of the parts under your hood. It could be a bad coil or another problem, so you need a mechanic at the dealership to check out the engine.

4. Your Engine Is Misfiring

You’re driving along normally, then you notice your car feels kind of jerky to drive. You come to a stop in traffic, and the car is vibrating really roughly, which is unusual for your vehicle. These are all signs that your engine is misfiring, resulting in strain on everything under the hood. A faulty coil can cause this issue, so you need to get your car checked out as soon as possible to avoid other parts under the hood becoming damaged.

5. Your Car Is Backfiring

You’re using your car normally, then there’s a loud popping noise that comes from the rear of your vehicle. It can be jarring, and it often indicates a problem with your engine, such as a faulty coil. This noise is just unburnt fuel igniting in your exhaust system, but it does mean you need to get your car checked out as soon as you can.
