Car stalls after few seconds?

Hi,

Have you checked to see if there are stored diagnostic trouble codes? If you haven't, I recommend doing that first.

Here is a quick video showing how it's done:

I realize most people don't own a scan tool. However, if that is the case, see if a parts store will lend one to you.

Next, a large engine vacuum leak can also cause issues. If you haven't checked for leaks, do that as well.

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

Start with this and let me know the results. Also, let me know if there were codes retrieved and what they are.

Take care,

Joe
