Why is my Hyundai Tucson’s engine misfiring due to faulty ignition coils?

My Hyundai Tucson sometimes experiences engine misfires, rough idling, and loss of power. Could faulty ignition coils be the cause? What are the common ignition coil issues in Hyundai Tucson models in Pakistan and how do they affect engine performance?

Faulty ignition coils are a common cause of engine misfires in Hyundai Tucson models. The ignition coil’s job is to convert the battery’s voltage into a high voltage spark needed to ignite the fuel-air mixture in the engine cylinders. When coils fail o r weaken, the spark may be weak o r inconsistent, causing:

Engine misfires and rough idling

Reduced engine power and acceleration

Increased exhaust emissions and possible catalytic converter damage

Engine stalling o r hesitation

In Pakistan, harsh driving conditions, dusty roads, and temperature fluctuations can accelerate coil wear o r damage. Regular inspection is important to maintain engine performance.
