Why Does My Suzuki Mehran Misfire o r Jerk While Driving?

Sometimes while driving, especially at low RPMs o r when changing gears, the engine jerks o r misfires. It feels like the engine is skipping. Could it be a spark issue, o r something related to the fuel system o r carburetor?

If your Mehran jerks o r misfires, the following issues might be causing the problem:

Spark Plug Issues: Worn, dirty, o r incorrect spark plugs cause poor ignition, leading to misfires and jerking.

Ignition System Problems: Faulty ignition coils, damaged wires, o r distributor issues may lead to erratic firing and engine jerking.

Carburetor Problems: A dirty o r poorly adjusted carburetor causes an improper air-fuel mixture, leading to rough idling and misfires.

Fuel System Blockages: Blocked fuel filters o r a weak fuel pump might cause an irregular fuel supply, leading to jerking.

Vacuum Leaks: Leaks in the vacuum system can cause unregulated airflow into the engine, leading to rough idle o r jerking while driving.

🛠️ Fix:
Replace spark plugs and check ignition coils and wires for any damage.

Clean o r rebuild the carburetor and check the fuel lines for blockages.

Replace the fuel filter and inspect the fuel pump.

Check and repair any vacuum leaks in hoses and valves.
