Hi Katie:
What you described could be several things. Is this something that just started? Is there anything you can think of that changes the issue? Also, you said when it's cold the engine revs high. Do you mean in park or neutral or does it happen when in gear?
If you could, let me know if things are serviced on a regular basis. For example, has the air filter been replaced.
Let me know.
Joe
