What are the signs of a failing ignition coil?
2 Answers
Signs of a failing ignition coil are usually quite noticeable. If your vehicle suddenly experiences abnormal shaking while driving, accompanied by a significant loss of power, it may indicate an issue with the ignition coil. Once the ignition coil malfunctions, it can cause the spark plug to stop working, leading to unburned air-fuel mixture in that cylinder. With one cylinder not functioning, the vehicle will experience power loss, and in severe cases, it may even stall. Additional information on vehicle maintenance is as follows: 1. Antifreeze usage tips: It's best to use antifreeze year-round. Besides its anti-freezing and cooling functions, antifreeze also has cleaning, rust-removing, and anti-corrosion properties, reducing radiator corrosion and protecting the engine. Be sure to choose the correct antifreeze color and avoid mixing different types. 2. Brake fluid usage tips: The performance of the braking system is closely related to brake fluid. When inspecting or replacing brake pads, rotors, and other hardware, don't forget to check if the brake fluid needs to be topped up or replaced.
I've encountered similar issues while driving before. If the car's ignition coil is faulty, there are some obvious signs to alert you. For example, the engine starts shaking violently, like driving on a massage chair, and there's a noticeable lack of power during acceleration, making uphill climbs or overtaking particularly strenuous. Fuel consumption can also suddenly increase significantly—my previous car's fuel consumption rose from 8 liters to 10 liters, and I initially thought it was due to driving habits. Starting the car becomes troublesome too; sometimes, you have to turn the key several times before it starts. Even more annoying is when the check engine light on the dashboard comes on, like a little warning. If ignored, it could damage the spark plugs or catalytic converter, leading to more expensive repairs. I recommend getting the ignition system checked at a garage as soon as you notice these symptoms—don't push through it, or you risk breaking down on the road, which can be dangerous. Paying attention to changes in engine noise and vibration levels while driving can save you a lot of trouble.
