1G very low idle

[1995 gst]

I just finished up all vacuum lines and now that everything is correct the idle is around 100-150 rpm, its just about to die and the screw that is supost to change the idle isnt there, its just an empty space? is there any other way to change the idle up besides the screw and why is my screw not there?

have you tested your isc coils? also what screw are you refrencing? the biss screw that is on top of the TB or the small set screw looking thing that actually opens the trottle. I would first search on setting the TPS and ISC first and see if that helps. Mabie you messed up a vac line somewhere as well. Did it idle good before?

Get a new screw. Your probably leaking there.

The screw im talking about it the idle screw, it connectes to the ics and when you screw it left or right it idles up or down, its just might seems to be blocked off by concrete from whom ever owned it last. all lines are correct and it did idle good before but it was because it was losing vacuum.
