Park the car in a safe location and turn off the engine.
Open the bonnet (hood) of the car.
Locate the idle speed adjustment screw. On the Renault Clio 1.2, it is usually located on the throttle body. It is a small screw, usually marked with an "I" or "idle."
Start the engine and let it run for a few minutes until it reaches its normal operating temperature.
Use a suitable tool, such as a screwdriver, to turn the idle speed adjustment screw. To increase the idle speed, turn the screw clockwise; to decrease the idle speed, turn the screw counterclockwise.
Adjust the idle speed until it is between 900 and 1,000 RPM (revolutions per minute).
Turn off the engine and close the bonnet (hood).
Remember, adjusting the idle speed can affect the overall performance and fuel efficiency of the car, so it is recommended to follow the manufacturer's specified idle speed range. If you are unsure about the adjustment process, it is advisable to consult with a qualified mechanic or refer to the vehicle's owner's manual for more specific instructions.
