Engine Performance: An ignition coil plays a crucial role in the ignition system of your vehicle. It converts the low-voltage electrical energy from the battery into a high-voltage spark that ignites the air-fuel mixture in the engine's cylinders. If one of the coils fails or goes bad, it can result in a misfire or a complete loss of spark in the affected cylinder. This leads to reduced engine performance, rough idling, and shaking or jerking during acceleration.
Warning Light: When the Check Engine Light (CEL) or any other relevant warning light flashes or illuminates on your dashboard, it indicates that there's an issue with your vehicle's systems, including the ignition system. A flashing CEL, in particular, often signals a severe or urgent problem that requires immediate attention.
Driving with a Faulty Coil: Driving with a coil gone and a flashing light can further exacerbate the problem and cause additional damage to your vehicle's engine and other components. When an ignition coil fails, the unburned fuel and air mixture can build up in the cylinder and lead to the overheating of components like the catalytic converter and exhaust system. Moreover, driving without a properly functioning ignition system can cause the engine to run lean, resulting in excessive wear and tear on critical engine parts.
Safety Risk: A malfunctioning ignition system, especially one with a flashing warning light, can compromise your vehicle's overall performance and reliability, increasing the risk of an accident or breakdown on the road. It is essential to address any flashing lights or warning indicators promptly to ensure your vehicle's safety and longevity.
If you notice a flashing light or experience symptoms of a faulty ignition coil or any other automotive issues, it is highly recommended to pull over to a safe location and either troubleshoot the problem yourself (if you have the knowledge and tools) or contact roadside assistance or a professional mechanic for further evaluation and repairs. Do not continue driving with a known issue that could put you, your passengers, and other road users at risk.
