At starting ,everycar need to run at fast idle mode to heat up the catalytic converter as fast as possible to cater for emission which is the essence of the high rpm starting and then goes into close loop mode after attaining certain temperature threshold which is when the rpm start going down .At cloop loop mode , vehicle fuel consumption is at its lowest by taken in Oxygen sensor signals
All these are algorithms written into the ecu to achieve near zero emission,so it just a normal condition.
