If your car is fuel injected, you probably have a vacuum leak or a bad idle control valve. Check for proper vacuum with a vacuum gauge and check the vacuum lines for leaks. If that's OK, it might be the idle air control valve, or I think Ford calls it the air bypass valve. It should be mounted on the side of the throttle body and it has 2 wires going to it. I'm not very familiar with your car but if the valve is the same as on other Fords, I could tell you how to check with an ohmmeter. What size engine do you have?
