The Impact of a Faulty Ignition Coil on Your Car

What Happens if You Drive with a Bad Coil?

The ignition coil plays a crucial role in ensuring optimal combustion of the air-fuel mixture in the engine, which is essential for smooth acceleration and refined power delivery. The ignition coil is responsible for providing the correct voltage to the spark plugs as the 12-volt battery is unable to produce the high voltage spark required. A faulty ignition coil can lead to various engine problems, so it is essential to know the symptoms of a malfunctioning coil.

Modern gasoline engines rely on ignition coils to create high voltage in the spark plug and produce the spark that ignites the air-fuel mixture. The primary and secondary winding of electrical cables are the crucial components of the ignition coil. The ignition coil works like an up transformer to induce high voltage in the secondary winding produced by the low voltage in the primary winding. Voltages can be increased from 300-400 volts to around 40kV. Depending on the vehicle model, ignition coils can be single-spark or multi-spark.

Symptoms of a bad ignition coil may include a decrease in engine performance and acceleration loss, difficulty driving uphill or maintaining highway speed, and the illumination of a warning light on the dashboard indicating a problem with the ignition system. Driving with a faulty ignition coil can cause damage to the cylinders, the electrical system, or the exhaust system of your vehicle.
