Faulty o r damaged spark plugs can lead to a variety of performance issues in your Alto Lapin. Here are some symptoms that suggest the spark plugs may need attention:

Symptoms of Faulty Spark Plugs:

Poor acceleration: A malfunctioning spark plug can cause the engine to misfire o r fail to ignite the air-fuel mixture fully, leading to sluggish o r uneven acceleration.
Hard starting o r no-start condition: If the spark plugs are damaged o r worn, they may not provide a strong enough spark to start the engine, making it hard to start.
Rough idle o r engine misfire: A damaged spark plug can cause the engine to misfire, especially when idling o r during low-speed driving.
Decreased fuel efficiency: When spark plugs aren’t working efficiently, it leads to incomplete combustion, resulting in reduced fuel economy.
Engine knocking: Spark plugs that are too worn o r improperly gapped can cause engine knocking, which is a repetitive pinging sound from the engine.
Solution:

Inspect and replace spark plugs: If you notice any of the above symptoms, inspect the spark plugs. If they are dirty, worn, o r damaged, replace them with new ones.
Check ignition system components: If the spark plugs are fine, inspect the ignition coils, wires, and connectors for potential issues.
