How to Determine if the Ignition Coil is Faulty?
1 Answers
Methods to determine if the ignition coil is faulty: 1. When the engine is idling, the vehicle body shakes noticeably. Observe the exhaust pipe outlet; the exhaust gas flow has obvious intermittency, and the exhaust pipe shakes violently, with a clear "popping" sound audible. 2. While driving, when the engine speed is below 2500 RPM, the vehicle body shakes noticeably with weak acceleration, but the shaking disappears once the speed exceeds 2500 RPM. 3. Open the engine hood and observe the running engine; if the engine shakes significantly, this type of shaking is clearly abnormal and not part of the normal engine operation, with a very large shaking amplitude.
