The spark plugs and ignition coils play a crucial role in engine combustion:

Worn-Out Spark Plugs: If spark plugs are old o r worn, they will produce weak sparks, leading to incomplete combustion. This can cause sputtering, rough idling, and poor engine performance.
Faulty Ignition Coils: Ignition coils are responsible for generating the spark needed for ignition. If they fail, it can cause weak o r erratic sparks, resulting in engine sputtering.

To avoid this, its important to replace spark plugs every 100,000 km or as per manufacturer guidelines and inspect ignition coils for any signs of wear.
