To adjust the idle on a 1993 Subaru Impreza, first ensure the engine is at operating temperature. Then, locate the idle adjustment screw on the throttle body; it's typically near the throttle linkage. Turn the screw clockwise to increase idle speed or counterclockwise to decrease it, while monitoring the RPMs with a tachometer. After adjustments, confirm that the idle settles within the manufacturer's specified RPM range, and check for any vacuum leaks that could affect idle stability.
