Default 93 infamous sputtering/attempting to stall low idle issue

so ive been chasing this issue for weeks, like everyone else it comes and goes.
cps,iac,tps are all fine they've been tested, cps and tps have been replaced recently, ngk plugs were installed.
fuel pressure tested 32psi-on the low end but still within range
regulator seems ok, fresh oil change.
ive searched on here and read well over a dozen threads about said issue.
but if anyone else can add to it please lmk.
its an 4.0 ho 5spd model 4dr and its got 276k on it.

Is the clutch engaged or touching the pressure plate?
