The most common cause of this is a vacuum leak. Here is a guide that will help with this:

Also, here is a guide that will help with surging issues:

Basically we need to run through this and determine what the cause is. Clearly it could be a couple things but the most common are intake manifold leaks or hose leaks.

So here is a video that will help as well. It covers the same basic info but some people just prefer videos.
