What do you mean exactly? It is idling high around 5900? It shouldn't be like that. Usually when the car is cold and you start it up, the rpm's go up, and after like 30 seconds go down and idle more smoothly. If yours is that high, it is possible something is wrong. Perhaps your pedal sensor is acting up, it happened to me once too.

idle monitor use two inputs which is coolant sensor and throttle position sensor..
lets try the most easiest thing first.. try to remove intake nozzle and clean throttle body valve.. carbon deposit built up and it could make throttle sticky (you cannot tell because its electronic system) and clog air from coming intake..

I never heard of low idle being a problem. A problem is if your idle was at 1k rpms the whole time.
