I think I found the cause of my high idle:
Not just cracked, but snapped off!
I wasn't able to figure out how to get the insulating wrap onto the new EGR tube, so I left it off. I tied any wires (IAC) away from the EGR tube so as to not put them in harm's way. Is it going to be OK to run without the insulation?

Perhaps I shouldn't have taken on a Fiero that the original owner said he liked to work on, especially after it spent some time 'submerged'. At least the car was free.
