91 8V hard start long cranking on hot soak. cold great

i'd want to know which path inside the TB is leaking. air.?
blocking ports finds this, bottom side, finds it the most fast.
its not ISC nor IAC, they are closed, so there must be TB Damage inside,?
i dont have a real xray view of the TB, just that nice but physically inaccurate one from from SUZ. below.
see exit port below just to left of red idle air;
that is the big 3.8" hole, blocking that hole, id bet ends the leak.
water hole, checked,
5 drilling holes ,tiny blocked, with stock gaskets.
3/8" is ISC and bleed and iac outputs.
slot hole. this is ported vacuum to EGR and dash pot ,via vsv valves. the valves are closed at idle and no air can pass, so... cant leak to the slot.
this slot is ported vacuum, EGr has no vacuum until off IdLE AND DASH POT IS hard vacuum all time (evap and map have dedicated manifold nipples)

im sure the slot HOLE path is not failing, but did you pinch the dash pot and egr lines to see if they cause idle drops at idle.
the dash pot might extend doing that and raise idle.
but not drop idle rpm. pinched.

id bet the 3/8 inch hole leaks air. big time. why ,will take careful checks with blowing with mouth on it and listening with rubber hose to ear, moving end of
hose all over to find this hiss of your breath. "escape path"

its not the fuel pressure reg leakings vacuum its on the atmosphere side if TV
