1G idle issue

[93gsx80]

hey guys-
just having a hard time with this car idling. it likes to kill when starting up cold. so i messed with the biss screw a little and had it idling good. now it seems like from all the vibration the screw loosens its self during driving. was just curious whats the best way to keep this screw in place? or is it a bad screw? it moves extremely easy. otherwise i was thinking possibly wrapping the screw in plumbers tape?? maybe you can help old mittsu mechanic??

Replace the o-ring on the screw. And you can't set the idle properly just with the screw. The ECU has to be in a mode to accept the changes. Read this: http://www.plymouthlaser.com/biss.htm
