How can I identify a faulty ignition coil causing engine sputtering and leaks in my Suzuki Alto?

A malfunctioning ignition coil can cause engine sputtering and lead to fluid leaks in the engine. What are the signs that indicate a faulty ignition coil is responsible for the sputtering, and how can I spot fluid leaks as a result of this issue?

To identify a faulty ignition coil causing engine sputtering and fluid leaks in your Suzuki Alto, look for the following signs:

Engine Sputtering o r Misfiring: The most common sign of a faulty ignition coil is engine sputtering, especially at idle o r when accelerating. You may notice hesitation in the engine’s performance o r the vehicle shaking as it tries to maintain a steady speed.
Check Engine Light: A malfunctioning ignition coil often triggers the check engine light on the dashboard. You can use an OBD-II scanner to read error codes that may point to a misfire o r ignition coil issue.
Reduced Engine Power o r Poor Fuel Efficiency: Misfires caused by a faulty ignition coil can lead to decreased engine power and fuel efficiency.
Oil o r Coolant Leaks: While ignition coil issues dont directly cause leaks, the misfires may cause additional strain on the engine, leading to fluid leaks, particularly around the valve cover gasket, spark plugs, o r cylinder head.
Burnt Spark Plugs: A misfiring ignition coil can cause the spark plugs to wear out more quickly, so checking the spark plugs for signs of damage o r wear can help diagnose the issue.
Solution:

Use an OBD-II scanner to check for error codes related to misfires o r ignition system faults.
Inspect the ignition coils and spark plugs for damage o r wear.
Look for fluid leaks around the engine, particularly near the spark plugs and valve cover.
