What are the symptoms of a faulty car igniter?

Symptoms of a faulty car igniter: 1. The car body shakes noticeably at idle speed. When observing the exhaust pipe outlet, the exhaust gas flow shows obvious intermittency, and the exhaust pipe shakes violently with a clear popping sound; 2. While driving, when the RPM is below 2500, the car body shakes noticeably with weak acceleration. The shaking disappears when the RPM exceeds 2500; 3. The running engine exhibits significant shaking, which is clearly beyond the normal working condition of the engine, with a large shaking amplitude. An igniter refers to a device that can instantly provide sufficient energy to ignite coal dust or oil fuel and stabilize the flame. In cars, the igniter generally refers to the ignition coil.
When driving my sedan, I experienced a faulty ignition with very obvious symptoms. The car had difficulty starting - turning the key would make the engine whir but it just wouldn't catch, especially worse during cold morning starts. While driving, there was noticeable power loss - even flooring the accelerator felt sluggish, struggling to climb small hills. Another annoying issue was intermittent engine misfires - it would stall when decelerating or stopping, forcing embarrassing restarts in traffic. The check engine light would occasionally illuminate too. These signs likely indicate worn spark plugs or damaged ignition coils that need immediate repair. Otherwise, besides reduced fuel efficiency, breaking down mid-drive is too dangerous. I recommend getting a professional shop to thoroughly inspect the ignition system at the first sign of trouble.
