No way to adjust it's set by ECU.
Have you checked fuses in OVP relay (to right of battery) and vacuum pipes for leakes. After that check the aux air valve is opening correctly.

all cars are adjusted by ecu's but when you disconnect the power the car usually go through an idle learn procedure. I think also the problem might just be a gummed up throttle which using a thottle body cleaner spray could fix the problem
