I’m using Nissan Y11 wagon (year 2000), my problem is idle running speed is too fast, how I reduce idle speeds. Fuel consumption is very low per litre 6Km (1L/6Km)

Have the IAC (idle air control) cleaned and check the valve for an idle adjust screw. If equipped, you can adjust the idling speed, if not, the idle speed is computer controlled and you need to check for vacuum leaks etc.
