Why is my Suzuki Alto misfiring? Could it be the spark plugs?

I’ve been experiencing engine misfires in my Suzuki Alto, and it’s causing rough idling and poor acceleration. Could the spark plugs be the reason? What are the signs of faulty spark plugs, and how can I tell if they need to be replaced?

Yes, faulty spark plugs can definitely cause engine misfires in your Suzuki Alto. A misfire occurs when one o r more cylinders fail to ignite the air-fuel mixture properly, leading to rough running and performance issues.

Signs of Faulty Spark Plugs Causing Misfires:

Rough Idling: The engine might idle unevenly o r shake because the air-fuel mixture isnt igniting properly.
Poor Acceleration: If the spark plug isn’t firing correctly, the engine struggles to generate the power needed for smooth acceleration.
Engine Light: The check engine light may illuminate due to misfires detected by the engine control unit ECU.
Loss of Power: Misfires can lead to a noticeable loss of engine power, particularly when accelerating o r driving at higher speeds.
Solution:

Inspect the Spark Plugs: If you notice misfires, the first thing to check is the spark plugs. If they are dirty, worn, o r corroded, they should be replaced.
Replace if Necessary: Spark plugs should generally be replaced every 30,000 to 50,000 kilometers, depending on your driving habits and the type of spark plugs used.
