1990 lesabre ses problem

when you first start the car it runs real rough, so i have to let it idle for a min or it will stall out. but once i let it idle it is fine to drive until i drive it for about 45 min straight then the temp light comes on. i just turn the heat on and it goes off. but what could cause this. i changed the tps but it still runs the same. any suggestions.. thanks

Low coolant level, stuck theromstat, coolant temp sensor & idle air control are just a few suggestions.

Where did you check the coolant level, at the reservoir or the radiator? You may have air in the system. Basic diagnostics required here.
