Ok that to me sounds like you need to clean the throttle body it easy buy carburetor clean just srap a little inside the throttle body n clean it that will help you the problem is the trottle body gets dirty sticky and won't idle good n stall remember don't put to much. Just a few spats inside the when you put the hose back it might take a few minutes to start because of the amount also don't accelerat it to high when it start good luck

Have the catalytic converter checked at your local muffler shop...clogged...worn out...Hope this helps.

stalls (or misfires) tune up time, ever heard of a 60k mile service?
and get and injector balance test, sounds like they leak,
and the starts are doing so from the flooded state.

no crank.
repeat that again. the key switch has many posisitions
no (this era) car cranks, in the non run or start position so?
my guess, is the start position (spring loaded it is) is intermittant
and when starting you wiggle key , in the ST posistion and the starter
motor wakes up. this is a bad ignition switch, which love to go bad
with huge key rings, (heavy)
if car is A/T tranny, wiggle the shifter any time it dont crank
and, try starting in Neutral (fresh switch contacts there)

Stalls is a 2nd symptom and if the dash lights dont die.
then is not related to the ignition key switch.
that is the 12vdc power system is good and the EFI/engine has issues
try a tune up first. (its in the operators guide read that)

after tune up and drive 20-50 miles
now using any newer OBD2 scan tool scan the PCM.
got DTC'S? post them. DTC are ERRORS.

Hi Glen, Check all the vacuum hoses and make sure there are no leakages of air into the intake manifold. Check the plastic ducting between the air flow sensor and throttle body. It is advisable to have a diagnostic scan carried out on the vehicle. Regards John

You vehicle uses a Idle air control motor,(IAC) when you put a load on the vehicle (Drive or reverse) the ECM detects the load and idles up the IAC, even for the A/C (air conditioner) You can try a throttle body cleaning. or a new IAC

clutch needs adjustment or total replacement

Needs a tune-up.

change the module

it could be a clogged convertor, or theres a potatoe in the tailpipe.
