Idles high then touching gas causes it to shut off?

Hi,

If it has a high idle and then turns off when the throttle is touched, my first possible suspects are either an engine vacuum leak or a fuel pressure issue.

If you haven't, start by checking for leaks.

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

If you are unable to find leaks, then check the fuel pressure.

Here is a link explaining in general how that is done:

I attached the fuel pressure specifications below.

Do this and let me know what you find. Also, let me know if the check engine light is staying on when the engine is running.

Take care,

Joe
