How to Determine if a Car's Ignition Coil is Faulty?

[VonGianna]

Methods to determine if a car's ignition coil is faulty include: 1. When the ignition coil is faulty, the car body will shake noticeably at idle speed; 2. Observe the exhaust pipe outlet—the exhaust gas flow will show obvious intermittency, accompanied by severe shaking of the exhaust pipe and a clear "popping" sound. As gasoline engines evolve toward higher speeds, higher compression ratios, greater power, lower fuel consumption, and reduced emissions, traditional ignition systems no longer meet the requirements. The core components of the ignition system are the ignition coil and the switching device. Increasing the energy of the ignition coil enables the spark plug to generate sufficient spark energy, which is the fundamental condition for the ignition system to adapt to the operation of modern engines.
