Engine misfires in Suzuki Alto vehicles are often caused by issues in the ignition o r fuel system. Common causes include:

Faulty Spark Plugs: Spark plugs wear out over time and can lead to misfires if they are dirty, worn, o r have improper gaps. Misfires may occur during acceleration, deceleration, o r idling.

Ignition Coil Failure: If the ignition coils fail, they can’t properly send electrical signals to the spark plugs, causing a misfire. This issue is often accompanied by rough idling and poor acceleration.

Fuel Injector Problems: Clogged o r faulty fuel injectors can disrupt the proper fuel-air mixture in the engine, causing an engine misfire. Misfires will be more noticeable under heavy load o r high acceleration.

Vacuum Leaks: A vacuum leak can lead to a lean fuel mixture, which causes the engine to run erratically o r misfire. Leaks around hoses, gaskets, o r the intake manifold are common culprits.

Faulty Sensors: A failing mass airflow MAF sensor o r oxygen sensor can send incorrect readings to the engine control unit ECU, leading to poor fuel mixture and engine misfires.

Diagnosis and Solutions:

Inspect and replace spark plugs regularly, especially if they appear worn o r dirty.
Test and replace ignition coils as needed to ensure proper firing.
Clean o r replace clogged fuel injectors.
Check for vacuum leaks and replace any damaged hoses o r gaskets.
Use a diagnostic scanner to check for error codes, particularly for faulty sensors.
