How do you adjust the idle speed on a Nissan Micra?

To adjust the idle speed on a Nissan Micra, first, ensure the engine is at operating temperature. Locate the idle adjustment screw on the throttle body; it may be covered by a plastic cap. Turn the screw clockwise to increase the idle speed or counterclockwise to decrease it, checking the RPM with a tachometer after each adjustment. Always refer to the vehicle's service manual for specific RPM specifications and procedures for your model year.
