10. Adjust the engine's base engine speed at idle.
Caution! If the engine idle speed "floats" after adjusting the base engine speed, disconnect the wire from the negative terminal of the battery for 10 seconds or more. Then connect the wire to the negative terminal of the battery, start the engine and let it idle for 10 minutes.
