Resolved what goes here? BISS hole on throttle body

[LTQuick]

What goes here. Whatever it was went missing and made my car not idle. I stuck a rubber vacume line cover thing in there to plug it up but and now it idles, but what is suposed to go there? Thanks

-BISS, base idle set screw, can be found at dealer or junk car, it has a O-ring on the screw for you to set the idle rpm.

Mitsu part # is MD614948 and it's called, "Adjusting Screw, Throttle Body". You need a #5 O-ring (3/8x1/4x1/16, available at most hardware stores), now available as Mitsu part # MD608806.

just get the screw from the dealership, i think it cost me around 3 dollars. just get the o-ring at home depot or whatnot. satan wants about 7 dollars for the o-ring and i got it at home depot for 17 cents
