are thjere 2 types of idle control valves on a 94' d15 monopoint? i only found the big one on the right with the coolant passage in it. is there a fast and a slow one? because idle bounces from 600 to 1000 rpm.....
thanks!

if im understanding correctly, you are lookig for the FITV (Fast Idle Thermo Valve)and IACV (Idle Air Control Valve)

the FITV is located below the Throttle body and the IACV is located on the back part of the Intake Manifold..

FITV is the fast idle thermo valve and controls your car while it's warming up. When it's out of warm-up mode and is idling regularly your idle is controlled by your IACV (Idle air control valve).

In short, yeah, both of them can cause this problem. IACV could easily if it's sucking air, sometimes the FITV's get jammed & need to be cleaned, **** like that. Remove each and clean it (the IACV might need a replacement), then replace the gasket when you put it back on, see what's happening from there.
