hmm... that 2500 rpm is weird.. try closing your idle screw.. it's on the TB, it's a slotted screw. Turn it clockwise to close it, see if your idle goes down.

when it went up to 4 grand did you rev it, or was that it going on it's own?

post up pics of your intake manifold and throttle body and vacuum connections, maybe i can shed some light onto that.

I'm going to go take some more detailed pics of mine and upload them for you... it's a ZC but should be similar.

the last 4 pics are of my vacuum lines...
like i said before, it does'nt matter where they really go as long as they get to a vacuum source (aka the intake manifold)

The MAP, goes to the TB, the top of the Purge Cutoff goes into the Charcoal Canister, the Bottom of the Purge Cutoff goes into the Manifold. The Fuel Pressure Regulator also goes into the manifold.

Make sure that there are no leaks either, cause a vacuum leak will also cause a surging idle like you have. in other words, make sure every hole in the intake manifold or throttle body has a hose going into it!!

no, you have 2 holes that are open...
check this out, this barb MUST go to the MAP sensor..

the MAP sensor is the sensor pictured in the 2nd pic down from your post. it's plugged in upside-down with a line coming off of it.

This one also is unhooked and could be causing your leak...
if you don't have a vacuum tee and enough lines, just stick a hose in it and then plug the hose temporarily to see if it goes away.. thats part of your "fast idle control solenoid valve" which you dont have.

yep, or plug it up. you don't really need it, and it's letting extra air into the manifold as it sits, causing your surge, i think.
