REDUX, car has wrong parts on engine, below is for engines not parts swapped...
welcome!!!!
wow an easy one, 8valve TBI.
my vacuum page cover this as does the under hood vacuum map, (seen on all uSA cars then)
that VSV , right rear is EVAP hose to canister below. so hose 44 fell off, easy. goes TB base nipple, and is full vacuum running, so now leak air. and will race and may hunt.
but that vSV is closed at idle and will not suck air,
nor will VSV egr
but the VSV dashpot will suck air. idling.

knowing the rule of suck you can find those 3 possible paths (lol)
i see your dash pot red VSV has a broken vent filter on top, missing it is and see fracture zone, make sure that fracture zone does not cause valve to leak.
on this old tad crazy ecu
air leaks cause idle reg surging
illegal today. this.
but this car will.... like clock work. a bad act for un skilled driver with A/t like a young daughter.
car surging badly...
the ECU sees illegal RPM and hunts it madly with ISC.
my 91 does it too. so do earlier.
I think 1996 hunting was cured. not sure,
