You should be able to hear/feel the thrumming of the idle valve when you
turn the ignition on.  After driving a DigiJet van for ~15 years it freaks
me out sometimes.

Does it run okay at higher speeds?  If so, check your fuel pressure.  That's
a lot like what happened on my van when the regulator went - it was just
drowning at idle.
