Hi,

This could simply be an engine vacuum leak or the throttle body needing to be cleaned.

First, check to see if there are any leaks.

Here is a link that explains how it's done:

If no leaks are found, I would next check and clean the throttle body. If it is excessively dirty, it can cause a stall at idle.

Here is a link that explains how that is done:

I attached the directions for servicing the throttle body specific to your vehicle below.

Try these things and let me know the results.

Take care,

joe
