It sounds to me like the heater core is out. Have you noticed the floor wet recently? that's a sure sign of heater core issues. The other option is it will act like that if it has no antifreeze or water in the radiator, in other words the radiator is dry.

Just a suggestion if someone has replaced the thermostat its possible they installed it pointing in the wrong direction this could account for cold air and the guage reading over hot. , EzForJesus

What would cause a 1994 Pontiac Sunbird to overheat causing coolant to pour out of an elbow on the firewall and is this an overflow?

there should be 2 hoses going into that firewall for the heater core, it is probably bad. find the 2 hoses and connect them together until you can repair the heater core, at least it will be driveable. one end of the hose attaches to where the top radiator hose connects to the motor, and the other end is on the water pump towards the bottom of the opposite side.
