Symptoms of a Faulty Ignition Coil in the Cruze?

Symptoms of a faulty ignition coil in the Cruze are as follows: 1. At idle, the vehicle body shakes noticeably. Observing the exhaust pipe outlet, the exhaust gas flow shows obvious intermittency, and the exhaust pipe shakes violently, with a clear "popping" sound audible. 2. While driving, when the RPM is below 2500, the vehicle body shakes noticeably, with weak acceleration. The shaking sensation disappears once the RPM exceeds 2500. 3. Upon opening the engine hood and observing the running engine, it is evident that the engine shakes significantly. This shaking is clearly beyond the normal working state of the engine, with a large amplitude of vibration.
Last time my Cruze had an issue with the ignition coil, the whole car drove like it was convulsing. The most obvious symptom was the engine shaking violently, especially during startup and low-speed uphill driving. Stepping on the gas felt weak, acceleration was always delayed, and fuel consumption skyrocketed. Normally, a full tank could cover 500 kilometers, but at that time it barely reached 400. The most annoying part was the sudden illumination of the warning light, a little yellow light flashing constantly. Once on the highway, the car suddenly jerked and almost stalled, giving me a real scare. Later at the repair shop, they diagnosed it as aging ignition coils causing the spark plugs to misfire, leading to incomplete fuel combustion and all these weird symptoms. If not fixed promptly, excessive carbon buildup in the engine could make things worse, even damaging the catalytic converter, which would be extremely expensive to repair. My advice: check it at the first sign of shaking, don't delay.
