Car starts hard then idles roughly for 2-3min then stalls and dies

Vacuum leak

why ignore the CEL??????
you cross over the spark wires. lost firing order.
its not PVC but is due.
sure, lost spark, lost spark time, crossed wire.
if spark is good try test fuel
clean the EGR, if it sticks open car will never idle fast.
and will stall.
clean the ISC do the ECU can in fact now control idle.

you are are on track, most here are not.
you did a tune up, that is good , and is first.
bad fuel, car parked for year, dead?
now the 1 question, (after it runs)
can your happy right off save the stall
only this counts..... 1st....

check firing order now that wires are scrambled.
then check for spark on all 4 cyl spark wire ends.
then if spark is good,
and compression, good, 150 not 80psi
you do know this is and inteference engine right? and if not
fresh timing belt the engine will grenade. for sure.
dont listen to dorks telling you, mine didnt, they are idiots.
if you like Russian roulette ? and $3000 new motors are joy?
then skip the belt.

that finishes off a 60k turn up, spark , filters and da belt.
then spark timing.
then fueling.

all the fuel in the world is useless on a dead motor or dead spark'.

fueling is last.
if motor and spark are good, then yes, fueling
try test fuel (spary)
if that works for duration of spray
then check fuel pressure
that be next.
and more... ask

change the fuel filter and check the fuel pressure

Do It Yourself Diagnosis and Repair

Have a qualified tech do diagnostic's on it !
003 Fuel System Tests Scan Data Tests

the distributer cap is probly worn-inspect--throttle body may need cleanin/also idle air contol/egr valve--get vehicle scanned its an OBD I system

to reset the computer simply unplug the battery for about 30 minutes.

However, you have a different problem I believe. you need to check your plugs and wires/coil packs. A fouled spark plug will cause rough running at any speed.

look at spark plug 6 see if it is foul out with oil. when you first start you car up and it smokes blue you have leaking valve seals and stop up oil return holes.if all is good .check 6 injector make sure its getting power.

Check if fuel or spark problem,..all engines need both to run...use starting fluid in air intake ,..if it runs very shortly-fuel pmp?,,ck for spark at spark plug,work your way back..also ck timing belt-intact? Kev-MN

change your oxygen sensor thet is whyoillight lights on
