What are the symptoms of a faulty ignition coil?
1 Answers
Automobile ignition coil failure symptoms: 1. Exhaust pipe vibration: When idling, the vehicle body shakes noticeably. Observe the exhaust pipe outlet - the exhaust gas flow shows obvious intermittency with severe pipe vibration, accompanied by clear "popping" sounds; 2. Significant body vibration: During driving below 2,500 RPM, the vehicle body shakes noticeably with poor acceleration. The vibration disappears when exceeding 2,500 RPM; 3. Obvious engine vibration: When opening the hood to observe the running engine, significant shaking is visible. This vibration clearly exceeds normal engine operation parameters with substantially larger amplitude.
