1993 Chevy Lumina stalls from a stop.

CHECK THE BRAKES SOMETIMES THEY WILL DRAG IN FORWARD

When it stops running and will not start back up, you'll need to figure out if you are lacking spark or fuel pressure to proceed with testing.

Read OBD for codes. Reset ECU and try again.

if you unlplugged the temp sensor so the fans will run the cars computer cant read engine temp and will call for to much fuel which will run good when cold but bad when warmed up

try the throttle position sensor

Unplug the temperature sensor and see what happens. If no change then the temp sensor plug maybe plugged somewhere it should not be. Sometimes it isb possible there are missmatched sensor connectors.

Free things to try: Take it to Auto Zone or some auto parts store and they can check the battery, alternator, and hook the thing to their computer to look for trouble codes for you.

Things you have to pay for: Take it to the auto shop and have them check the timing, spark plugs, and they can translate the trouble codes into language you understand.

it sounds like you need to inspect your spark plug wires and spark plugs. if they are ok it could be your coil

a few things to check .. make sure all vacuum lines are on . next check the EGR valve its very bad at stalling at stop signs and quick stops .. and does it run good down the road ? thanks Jerry and holler if you have more ..

best thing is to put a diagnostic comp and check for any faults!! could be somethin simple like plugs and leads
