How to Repair a Faulty Ignition Coil?

[EmersonMarie]

As part of the engine ignition system, the ignition coil plays a crucial role in converting low-voltage electricity into high-voltage electricity. Repairing an ignition coil not only requires specialized automotive knowledge but also involves certain risks when dealing with the ignition system. Vehicle owners should directly visit a 4S dealership for repairs. Symptoms of a faulty ignition coil include: 1. Engine shaking—once the ignition coil is damaged, the spark plug may fail to ignite the air-fuel mixture, leading to engine misfire and severe shaking. 2. Increased fuel consumption and reduced power—as the spark plug's firing capability weakens, the engine may exhibit adverse effects such as higher fuel consumption and decreased power. 3. Excessive carbon buildup—weakened spark plug firing can cause incomplete combustion of the air-fuel mixture, resulting in the formation of carbon deposits, a type of coked substance.
