Welcome. Can you describe more about what you are experiencing? Does it only stall occasionally, only when cold, only when hot? Are you getting any Diagnostic Trouble Codes (DTCs)?

Replace the battery recently? Complete the idle learn? Check the MAP sensor under the silver intake manifold.

Fuel pump wire harness at the connector under the car can be bad. When the car is running, get under there and wiggle it, and tug on the wire a little, and see if the car stalls. Also, although rare on a '94 random stalling can be faulty crank sensors or the wireing. It is correct that codes should be retrieved, but a car this old, wiggleing wires sometimes finds the gremlin.

This is OBD1, you have an ISC on that engine. ISC = Idle Speed Motor

It could need cleaning or adjustment. Do you hear it clicking? Has it been adjusted?, along with the Minimum Air and TPS?

Do you have any P codes either history or current?

Here is info on the ISC from Barry94, he has STS

Crank Sensors as winterset noted can also cause that type of stalling. I cant remember if crank sensors set a code in OBD1
