High Idle??? how to adjust??

[GTi-R done]

Just got my 92 gti-r over hear in the states. Im familier with the Bluebird motors but havnt played to much with the Quad throttle body setup. My car is idle between 1500-1800rpm. How do i adjust and lower that?? Ive heard of some quad throttle setups having to be adjusted by each individual butterfly.hope thats not the case with nissans.
Any help would be much appreciated.

thanks
