could be a bad TPS throttle position sensor OR a bad IAT idle air control temp sensor.
The 95 Lumina with a 3.1 engine does not have a temperature sending unit. Instead, the dash temp gauge is controlled by the engine coolant temp sensor. This sensor is located on the driver's side, top of the engine.
There are several sensors on a 1995 Neon. The water temp sensor, crank shaft position sensor, and oil temp sensor are all mounted at various places on the engine block.

the air temp sensor should be located on the radiator support behind the grille. Sometimes around the headlight area or attached to the center/ latch supports

The 1995 Nissan: temperature sensor is located on the front of the engine. The coolant temperature sensor will be near the thermostat housing.

could be several things. 1st is the car actually overheating. If so then it could be a stuck thermostat or a bad water pump. If it is not really overheating my bet would be a falty temp sensor. The temp sensor is what actually tells the light to turn on.
IAT= intake are temperature sensor ECT= engine coolant temp. sensor
The temp sensor for the ECM (engine control module) is next to the thermostat housing.
