I'd check a few other things first - if it's idling fine when warm (and
keeps a stable idle when you load it up by turning on the a/c compressor)
chances are it is not the idle stabilizer valve (which is not cheap BTW).

First check your coolant temp sensor.  It is a dual function (ignition/fuel)
sensor located right above the #2 plug (if I remember right).  It tells the
FI that the engine is cold and compensates accordingly; your cold
idle/starting characteristics would suck if it wasn't working.

If that's OK check the cold start injector, which sprays extra gas at a cold
start.  It could be plugged/broken.

Those are the easiest to try...can't remember if the '84 5000 had the engine
error code diagnostics...if so check those first to see if you have any
error codes........SLM
