Hi,
The most common issue that causes a rough idle and stalling is an engine vacuum leak. If you haven't already checked, that is where I would start.
Here is a link that explains how it's done:

If you find no leaks, the next thing is the idle air control valve (IAC). The IAC is responsible for maintaining the engine idle speed. It can become dirty and or damaged. That is what I would check next.
Here is a link that explains how to service one:

If you look below, I attached a link that covers in more detail what I discussed. Take a look through it and let me know if it helps.

Let me know what you find. Also, let me know if the check engine light is on and if you know of any codes stored.
Take care,
Joe
