What are the signs of a failing ignition coil?

[JesseLee]

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.
