RPM not stable when ideal

[apexivafc04]

the throttle body also ITR. may i know how to tune the sensor??

The sensor sit beside the tro. body and it is black one. U can loose the 2 nut and adjust it left or right. But the better way is to ask ur mechanic to adjust for u.

Did ur rpm become not stable after WOT?

using this setup for more than a year already. It's like intermittent, especially during day time, but it's not that serious furthermore already get use to it...
Coz i am using CTR cams, if use back the stock ECU which fuel cut at around 8000, no syiok...

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.
