Do you have any code's?Sound's like you could have a vacuum leak those cars are known for the intake gasket leaking around the number one intake port.As far as the heater blowing cold on the 3rd and fourth speed setting you could have restricted flow in your heater core.Is both your upper and lower radiator hose getting hot?Also is both your heater hose's going into the firewall getting hot?
