How do you adjust the idle on a 1994 Toyota pickup?

To adjust the idle on a 1994 Toyota pickup, first, ensure the engine is warm and in park or neutral. Locate the idle adjustment screw on the throttle body, which is typically near the throttle linkage. Turn the screw clockwise to increase the idle speed or counterclockwise to decrease it, while monitoring the RPM with a tachometer if available. After adjustments, check for smooth engine operation and make any necessary fine-tuning.
