1998 Pontiac Grand Am Question: my car is running hot while sitting still

The first checks if your 1998 Pontiac Grand Am is running hot while sitting still would be the coolant level and the cooling fan operation. If the coolant level is full and the fans turn on when the engine gets warm then check the temperature of the air the fans are blowing, if it is cold then you may have a stuck closed thermostat or some other issue causing poor coolant flow.
