Can the car still run if the ignition coil is broken?
2 Answers
If the ignition coil is broken, the car cannot run. One of the core components of the gasoline engine ignition system is the ignition coil. For the mixture in the engine cylinder to combust, ignition energy is required, and the ignition coil serves as the medium to provide this energy, completing the ignition action through the spark plug. Symptoms of a faulty car ignition coil: 1. Weak acceleration accompanied by shaking; 2. Reduced ignition energy provided by the ignition coil or electrical leakage may cause the engine to shake at idle, and abnormal engine noises can be heard; 3. The engine fault light on the dashboard will illuminate, indicating a fault; 4. The mixture in the cylinder may fail to combust, adhering to the three-way catalytic converter and causing blockage, leading to engine stalling.
Last time my ignition coil had a problem, the car could barely start and shook violently when driving, like dancing. The speed couldn't exceed 50 km/h, the dashboard warning lights were flashing wildly, and after driving for a while, it completely stalled on the roadside. After towing it to the repair shop, it was found that the spark plugs were also burnt out, costing an extra 1000 yuan to fix. If I had gone to check it earlier, the problem wouldn't have escalated. This kind of thing happens often; a faulty ignition coil can cause abnormal engine operation, and continuing to drive may damage the catalytic converter or oxygen sensors, multiplying repair costs. Now I regularly check the ignition system and have a friend help inspect the plugs and wiring every year—prevention is always better than regret after the fact.
