If you have the stock chip, replace it with anything else modern. The start up on the stock chip was terrible.
Correct idling

Hey Masashi, welcome to the board, you gotta be one of the few guys with a GN in Japan, sweet.
My guess after reading his post was, from all the 38 years of driving, the TB blade screw is a tad out from bouncing.
Or maybe the stock chip commanded a low idle rpm, not sure anymore, anyone remember???
Before you turn in the screw on the throttle body, wait to hear some other replies.
If you do turn IN the screw to open the TB blade a tad, you'll then have to adjust the TPS and most likely the IAC/ISC will drop a tad. The OEM chip might command 700rpm, I can't recall factory idle rpm.
