Car has started idling poorly upon start up. The tach is dancing between 900-1300rpm on its on, then it usually dies. Between 1300-2000rpm w/ a little gas, then it idles properly after about five minutes of the latter.

My throttle plate only closes about 88% of the way. It sounds like fuel isn't making it into the to (venturi? float bowl?) or something. Afraid if I go to on the local shops they'll just tell what they think I want to hear and overcharge me for it.
