To adjust the idle on a 1992 BMW 735i, locate the idle air control valve (IACV) on the throttle body. Start the engine and allow it to reach normal operating temperature. Then, using a screwdriver, turn the adjustment screw on the IACV clockwise to increase the idle speed or counterclockwise to decrease it, checking the RPMs frequently with a tachometer. Ensure that the idle is set within the manufacturer's specified range for optimal performance.
