Faulty ignition coils impact performance by:

Causing Engine Misfires: This leads to rough running, loss of power, and increased emissions.

Lowering Fuel Efficiency: Misfires waste fuel and reduce mileage, which is especially costly with Pakistan’s fuel prices.

Increasing Engine Wear: Persistent misfires can damage the catalytic converter and other engine components.

Triggering Warning Lights: The car’s diagnostic system will detect irregularities and alert the driver.

Reduced Smoothness: The engine may feel sluggish o r unresponsive, particularly noticeable in stop-and-go traffic common in Pakistani cities.

Maintaining healthy ignition coils is crucial to keeping the S-Class running smoothly under these conditions.
