Could a Faulty Ignition Coil Be the Cause of Engine Sputtering in Suzuki Alto Lapin?

How does a malfunctioning ignition coil contribute to engine sputtering in the Suzuki Alto Lapin? What are the typical symptoms of a failing ignition coil, and how does it affect the spark plug’s ability to ignite the air-fuel mixture? Can ignition coil issues be easily diagnosed, and what would the repair process involve?

Yes, a faulty ignition coil can cause engine sputtering in the Suzuki Alto Lapin by disrupting the ignition process:

Ignition Coil Function: The ignition coil is responsible for generating the spark that ignites the air-fuel mixture in the engine’s cylinders. If the ignition coil is faulty, it may not generate enough voltage to create a strong spark, leading to incomplete combustion and engine sputtering.
Symptoms of a Failing Ignition Coil: The most common symptoms of a bad ignition coil include sputtering, misfires, poor acceleration, rough idling, and an increase in fuel consumption. The engine may also struggle to start o r may stall at idle.
Diagnosis and Repair: Faulty ignition coils are usually diagnosed through misfire codes in the engine control unit ECU o r by inspecting the ignition system. Replacing the faulty coil is typically the solution, and the ignition system may need to be tested to ensure no other components are affected, such as the spark plugs o r wiring.
Replacing the ignition coil can restore the engine’s smooth operation and prevent further misfires.
