an A9S is fine, something else is wrong.

Check for codes - http://www.my5oh.com/forum/viewtopic.php?f=36&t=923

Check vacuum, how much does it pull at idle?

Check timing, what's it set at with the spout pulled?

Check fuel pressure, what's it set at with the regulator vacuum line disconnected and blocked?
