Could you give me more info what colors/location in the ISC socket are the 12v wires?

Yeah check the ISC wiring. My FTO was idling crap at idle for 5
years! I checked and repaired the 12v feed to the ISC and it solved
the problem. There are 2 12v feeds on the wire.

some time now. ISC is the usual suspect, but I have tried several
ISCs supplied by a japanese surplus supply shop here in manila but
to no avail. Cleaned the throttle body, changed my air flow sensor,
adjusted the tps, BISS, and accelerator cable screw  ... nothing
worked.

which turns on at the same time with the A/C compressor and have
their relays separated. Partially i meant when the A/C compressor
turns on, my RPM still drops dramatically but after 3-5 seconds, it
regains to about 950 rpm.

done though.
