Rough idling o r engine vibrations can be caused by multiple engine o r fuel system issues. In Pakistan, poor fuel quality often leads to incomplete combustion, causing engine misfires o r uneven idling. Worn spark plugs, dirty fuel injectors, o r faulty ignition coils also contribute. Additionally, vacuum leaks o r malfunctioning sensors like the mass airflow sensor o r oxygen sensor can disrupt the air-fuel mixture. Regular servicing, timely replacement of spark plugs, and using good-quality fuel help reduce these symptoms. Diagnosing sensor faults with a scanner tool can also pinpoint issues early.
