What's up Fitz? Engine coolant temp tells the computer how much fuel and air to send. On startup, the engine needs all the fuel and air it can get. When the engine coolant temperature sensor realizes that the engine is warming up (i.E. The temperature of the coolant flowing across the sensor) the computer retards air and fuel mixture.
These models of Oldsmobiles as well as other GM cars with the same platforms had high failure rates of the ECM (engine control module) or engine computer. It would help to see if the OBD1 (first generation) will allow you to communicate with it.
How long can you keep it running before it dies?
