What causes rough idle on petrol cars?
The most common cause is a dirty throttle body — carbon buildup causes irregular airflow at idle. GarageNation cleans throttle bodies with chemical spray as part of major service (included). If cleaning doesn't fix it, the next steps are spark plug inspection (₹3,500–₹8,000 for a full set), ignition coil test, and intake leak test.
