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,
Thanks for the reply. I have looked at the diagram you posted before. I understand that the #44hose will go to the TB. Problem is, I have looked all around the TB and intake for the nipple to plug it into. As you can see by the pics, there is no visible nipple anywhere to connect to. I have felt all around, blindly in most cases for the nipple and just cant find it.
As for the Red VSV, the missing cap, you mentioned it is a vent??? It's ok to run it without this cap? If not, any suggestions as to where I can get a new VSV?? Again thanks for your help
