Hi and thanks for using 2CarPros.com.
There could be a few things which cause an engine to stall. First, if the check engine light stays on when the engine is running, you need to scan the computer for trouble codes. Here is a link showing how that is done:

I realize most people do not own a scanner, however, most parts stores will do it for free.
Next, here is another link that describes causes for engine stalling:

The next concern deals with an engine vacuum leak. Here is a link that shows how to check for one. You will need a vacuum gauge. Most parts stores will lend or rent one to you.

Let me know if these help or if you have other questions.
Take care,
Joe
