A faulty ignition coil in a Suzuki Alto can cause engine sputtering and lead to fluid leaks for several reasons:

Incomplete Combustion: The ignition coil is responsible for providing the spark needed to ignite the air-fuel mixture in the engines cylinders. If the ignition coil fails, it may not deliver a strong enough spark, resulting in incomplete combustion. This can cause the engine to sputter o r misfire, especially at idle o r during acceleration.
Engine Overheating: A misfiring engine puts additional stress on other engine components, which can cause them to overheat. If the engine overheats, it can lead to oil o r coolant leaks due to cracked seals, gaskets, o r damaged components.
Increased Engine Pressure: Persistent misfires can increase the pressure inside the combustion chamber, which may cause damage to gaskets o r seals around the cylinder head o r spark plugs, leading to oil o r coolant leaks.
Oil Leaks around Spark Plugs: If the ignition coil is not functioning properly, it can cause the engine to run rough, leading to oil buildup around the spark plug area. This could cause oil to leak, particularly if the valve cover gasket is already worn out o r damaged.
Solution:

Inspect the ignition coil, spark plugs, and related wiring for damage o r wear.
Replace the faulty ignition coil and ensure all related components, such as spark plugs, are in good condition.
Check for leaks around the spark plugs, valve cover gasket, and cylinder head.
