Why is my Alto Lapin experiencing rough idling o r misfiring?

I’ve noticed that my Alto Lapin’s engine is idling roughly and sometimes misfires, especially when the engine is cold. Could this be due to a spark plug issue, and what are the possible causes of rough idling o r misfiring related to spark plugs?

Rough idling o r misfiring in your Alto Lapin can often be caused by faulty o r worn-out spark plugs. Spark plugs play a crucial role in igniting the air-fuel mixture in the engine, and if they are not functioning properly, it can lead to incomplete combustion, resulting in rough idling o r misfires.

Possible Causes:

Worn o r fouled spark plugs: Over time, spark plugs can become worn o r fouled with carbon deposits, oil, o r fuel residue. This can cause poor combustion and misfiring, especially at low RPMs.
Incorrect spark plug gap: If the spark plug gap is too wide o r too narrow, it can cause weak sparks, leading to rough idling o r misfires.
Dirty o r damaged ignition system: Issues with the ignition system, such as faulty spark plug wires o r coils, can also cause misfiring.
Solution:

Check the spark plugs: Inspect them for wear, carbon buildup, o r damage. If necessary, replace the spark plugs.
Ensure proper spark plug gap: Make sure the gap is set according to the manufacturers specifications.
Inspect the ignition system: If the spark plugs are fine, check the ignition coil, wires, and other components for faults.
