#1 is the idle adjust screw. Follow the line from that; it points into a hole above the TB bore, positioned at about 11 oclock.
ps... The procedure for adjusting the "BASE" idle:
First, the mechanical stop for the actual throttle plate should only just barely prevent the throttle from wedging stuck closed.
Engine warmed up with all electrical loads turned off.
Unplug the IACV (#9). (idle will drop down to 'base' idle)
Adjust idle to 600?? rpm. (look it up, some years are different)
Turn it off & reset the ECU. (pull #13 fuse in box near right-front door hinge)
Let it cool down. Plug th IACV back in.
Start & idle for 10 minutes WITHOUT TOUCHING THE GAS PEDAL AT ALL.
edit-oops: I forgot a step...
