most plugs are set for cars with super, high energy ignitions, wide,
this car is no anywhere near this level of spark energy.
the egr valves log to stuck open as you come to stop., this is because (sure its dirty valve) but happens as you come to stop the idle switch closes, and the EGR is commanded off line.
if the EGR sticks now , the engine stalls or goes to 500rpm and stumbles badly.
the EGR loves to stick on most old sidekicks.
at times it can be a real pain.
i think its got 2 problems now.
ok , like someone grabbed the crankshaft, sounds like total loss of spark to me. random.
that can be hard to find.
check the 3 ECU fuses for no corrosion , on there tips. IG coil, Dome and FI fuses.
dome wont cause this but is ECU fuse for memory.
the not responding to fast right foot actions, tell me it's not fuel.
The fast right foot sends excess fuel fast, via the injectors. NOW. fast, instantly.
if the fuel pressure was zero, at that moment, sure, but sounds to me like spark.
If the fuel pressure drops low and you will sense that first, but spark loss is NOW. like, Paul Bunyun grabbing the crank.
but who is doing that , the Dizzy?
id check connections to the DIZZY , make sure it's side plug is not loose.
and those extra grounds to it.

see G109?
see that right side of that table. see comments and what those do? 16v 95.
i think your DIZZY is dropping spark,. but don't know way. if the dizzy is dropping off line, code 42s should pop. or if ignite fails, code 41.
one other trick i do on some hard cases.
is to run a small new vacuum line to the plenum, to the EVAP nipple there and in to the cab.
and fitted to my propane torch , nozzle off, then when it stalls, have a helper crack open that propane valve, if this ends the Bad Event its Fuel if not spark.
easy huh...?... and very simple to do..
add fuel at the moment.
snake hose through the fire wall, keep it fitted to tank so it can';t suck air. (no nozzle does that)
what do you think? we do this all the time on engine, hood up and it stalls off idle. (ah lean your are, this cured it)
ps. and propane is a very very safe test fuel, unlike wet fuels.
your car has demons, lets kill em.
