Prior Question on 1992 Regal stalling

Temperature sensors are either variable-resistance sensors or on-off-switch sensors.
Temperatur-to-electricity sensor can mesure either engine coolant, air, or surface temperatur as needed.
Base on input from the temperatur sensors, the computer can adjust air-and fuel mixture or dump air into the exhaust system to prevent overheating of the catalytic converter.
Now back to the question if the problem could be the temperature sensor.
Check the fuel injection system, and still check for a vacuum leak too.
