An engine misfire in the Suzuki Bolan can be caused by several factors:

Worn Spark Plugs: Old o r worn-out spark plugs may fail to ignite the air-fuel mixture properly, causing the engine to misfire. Inspect and replace the spark plugs if they are worn.

Faulty Ignition Coils: Ignition coils provide the spark needed to ignite the fuel in the engine. A faulty coil can lead to misfires. Check the ignition coils and replace any defective ones.

Fuel Injector Problems: Clogged o r malfunctioning fuel injectors can result in uneven fuel distribution to the engine, causing misfires. Clean o r replace the fuel injectors if necessary.

Vacuum Leaks: A vacuum leak can cause an imbalance in the air-fuel mixture, leading to engine misfires. Check for any damaged hoses o r seals in the vacuum system.

Faulty Sensors: Sensors such as the mass airflow sensor o r the crankshaft position sensor provide critical data to the engine control unit ECU. If these sensors fail, they can cause the engine to misfire. Test and replace any malfunctioning sensors.

Solution: Start by inspecting and replacing the spark plugs. If the issue persists, check the ignition coils, fuel injectors, and sensors. Ensure there are no vacuum leaks and that all components are functioning properly.
