I tested some more after this post. I think when I got 88f I was reading for towards the valve part of the iac, where there probably isn't any coolant flow. I disconnected the hose going to the iac and used a bicycle air pump and pressurized the hose, coolant shot out of the iac. I also did it the other way and coolant shot out of the hose. So it sounds like the iac is junk. I'll shove some jb weld in there, that'l fix anything :-) Thanks for the help.
On another note, would that port being open all the time cause low vacuum? Just wondering if it had anything to do with my weak brakes....
