I had the same problem with my 93 Vortec. Its the regulator in theCMFI unit.
You will probably see leaking gas in the manifold area. I can't do my own
work ,but it cost me around $300. Change the tubes to the injectors also.

Actually, when the injector in my 94 went, the only symptom was hard
starting after it sat for about 30 mins and a VERY slight lope to the
idle shortly after start. It acted like it was flooded. Now, based
on the comment that they know it's running rich, I suppose the
injector and fuel lines are a fairly accurate diagnosis.
Now, when the EGR clogged, it ran well under load, but once it got to
idle, it practically stalled, it also set a code.
