What are the symptoms of a faulty ignition coil?
1 Answers
There are several symptoms when the ignition coil is faulty: 1. At idle speed, the vehicle body shakes noticeably. Observe the exhaust pipe outlet - the exhaust gas flow shows obvious intermittency, accompanied by severe exhaust pipe vibration and clearly audible "popping" sounds. 2. During driving, when the RPM is below 2500, the vehicle body shakes significantly with weak acceleration. Proper ignition coil usage methods: 1. Prevent the ignition coil from overheating or getting damp. 2. Don't turn on the ignition switch when the engine isn't running. 3. Regularly inspect, clean, and tighten wire connections to avoid short circuits or grounding.
