Switching to Neutral Gear at stationary saves Fuel? (4AT/CVT)

No worries.  It is normal.  As you engage N, the engine load decrease suddenly and spins faster as a result.  ECU will then automatically adjust the idling speed.

oh ya
with N = 800
with D = 600
With airocn on

Why?

detach8:
correct me if i am wrong...
the a/c pulls on the engine , also when you engage D your engine is actually engaged in gear to the torque converter, thus zapping up some power from you engine and reducing its idling speed

liewks:
With A/C on and compressor kicking in, and with gear shift in N, RPM's up to 800+ appear to be the norm.

With A/C off and in N, it is usually dead on at 700rpm.

but with aircon on, N=800, D=600, donno what logic is that. if so, then we shldn't switch to N leh.
