RPM not stable when ideal

[apexivafc04]

WOT stand for what??

WOT stand for work on throttle mean that u press the pedal with full throttle up to rpm limit.
I just want to know when is this unstable rpm will happen? When cold engine start up or after a full run?

oic... i tell u the symtom.

start engine - RPM = 1k

Once u running (only normal drive not full throttle) for a while the RPM = 1.5k to 2k when idle.

But sometimes it will back to normal.
