Ok heres the symptoms. My car during the day idles kind of low, like around 200-500 rpms. During the evening when its colder out it idles great. Around 700 rpms. What I want to know is where could the leak be? and how can I test for it?

Could this be a dirty intake? or valve? any suggestions would be appreciated.
