How Far Can You Drive with a Faulty Ignition Coil?

[MacNora]

It is possible to drive with a faulty ignition coil, but it will increase fuel consumption and reduce the engine's lifespan. The consequences of a faulty ignition coil are as follows: 1. A faulty coil can cause a misfire, leading to symptoms such as engine shaking, lack of power, and unstable idling. When a cylinder misfires, the air-fuel mixture in that cylinder fails to ignite and is expelled through the exhaust, increasing fuel consumption and carbon buildup, which further shortens the engine's lifespan. 2. The engine may stall while driving, and in severe cases, it may fail to start. Additional tips on protecting the ignition coil: 1. Pay attention to the condition of the spark plugs, as using worn-out spark plugs increases the workload on the ignition coil. 2. Monitor the engine coolant temperature, as overheating can easily damage the ignition coil.
