When I had this issue, I found, when I took off my IAC, it was black and disgusting inside. I cleaned it with contact cleaner, put it back on, and my truck started beautifully. Every once in a whilen it starts acting up again or the check engine light will come on, and that is the first thing i do, it never fails me. I supose replacing it would be a good idea, but if you're low on funds, just clean it up.
As for that vacuum line with no hose, did it make a difference when you capped it? That darn line has baffled me for years and my Chilton Guide doesn't seem to say anything about it. I am just curious.

I capped the line because it was direct access into the intake. It made a little difference, but not much. On the older Rodeos (96 and older), it was used with a check valve that connected to a steel vacuum line that ran along the frame rail on the drivers side back towards the tank.
The fuel and vacuum lines for the tank run on the passenger side of the 97 rodeo. Our manual nor the vacuum diagram show that line. I just capped it.
The only thing I can think of is that it goes to the transmission vent that sits in the corner of the engine compartment on the passenger side, but I highly doubt it.

Update: Problem fixed. It was a bad ignition module supplying bad information to the computer. Changed module and everything works fine now.
