Hi,

The most common cause of a rough, low idle is an engine vacuum leak. That is where I would recommend starting to check.

Here is a link you may find helpful; it explains what to check for when the engine stalls at idle:

Also, here is a link specific to locating and repairing an engine vacuum leak:

Let me know if this helps or if you have other questions.
