Just for closure, in case anyone runs in to the same problem. It's
finally fixed ... heh. I picked it up yesterday. There were two
leaking injectors, one leaking outside (they mentioned replacing an
o-ring), and one leaking into the intake. Hopefully this is *really*
the end of it.

Thanks to the group for all your replies.

Thanks.
Did they start leaking on their own or did someone pull them and
not replace the O rings?

Lots of expensive parts replaced for a simple problem. Did they
finally figure it out, or did you have to tell them how to diagnose
it?
