To me it sounds like you have a IAC motor that is not working or you have a vacuum leak. Here are two guides to helps us and I have included the IAC motor location and how to change it in the images below.

Here is the IAC motor location. There is a chance the EGR valve is leaking a little as well, but one thing at a time. Check out the images (below). Please let us know what happens.
