This sounds sort of like the loping idle you get if the idle speed is set too 
high. Try plugging the temp sensor back in and then turning the idle screw 
down to see if this cures it.

I see no reason to remove the IAD. Why not leave the IAD and pull the 
runners, so you can inspect the intake gaskets. If the gaskets are the correct 
brown plastic ones but need paper faces, fix that. If they are the metal Beetle 
ones, I have the correct FI ones. When you put everything back together, 
loosen everything and make sure the runners line up with the IAD ports 
perfectly.

Unless the short hoses have been badly distorted by poor alignment of the 
runners to the IAD ports, they are not likely to be a problem. Oily is normal.

BTW, I came across an old email from you that said you wanted a 
replacement 505 vac advance can. I have one now. Do you still want one?
