Default fluxuating idle until car is ran for awhile?

when i start my car, during warm up, when the rpm's reach or drop to 2k, i get a bad fluxuating idle. it only happens at 2k. after the car has been warmed up and ran, the prob goes away. anyone know what the problem could be? i'm using a obd0-obd1 conversion harness and hondata s200.

try taking off your IAC valve and cleaning it out. I know the ones off my cars were always dirty.

Have you bypassed your coolant lines to the TB and IAC? I know when I did this I had to play with the idle screw and the IAC duty cycle. Mine would only do it when it was cold outside and after a nice ride down the interstate until the under hood temps rose. But its fixable....

But check your IAC 1st.
