Is there any difference with the Integra iacv, Civic ek4 or ek9 one?

Also ordered new gaskets and need to know which iacv is my fitment (bottom two in the picture), is there anyway of spottin the difference without removing the unit (havent had a chance to look yet sorry!)

I think the second one from bottom left but best to remove it, there's just two bolts holding it on
 
I'm pretty sure all the obd2 iacv are the same. Is your iacv giving some trouble?
 
When it got cleaned out it seemed to help with the stalling problem a bit more so if they are decent money i think i will just replace it also and see how that goes :)

There not the cheapest item. Did you clean the port on throttle body that feeds air to it also? Is car still stalling since revs were increased?
 
Hasnt stalled so far but when im slowing down with the clutch pressed in, its revving at about 2000rpm and when the car stops the revs drop to about 1000rpm. Im really baffled now! :(
 
Have you checked to make sure you don't have a vac leak some where? And when idle was adjusted was it by base idle screw on throttle body or throttle cable been tightened to open t.b butterfly slightly?
 
Im not sure, ill be over on Monday and ill find out then sorry. Is there somehow i can check for vac leak please? :)

Listen for any hissing sounds and run finger down along any pipes leading away from intake manifold. Ill pm you another test to do tomorrow with pic.

I think there are the same. engine stalling problems can usually be traced to failure of the idle control valve. Like its name suggests, the valve controls the amount of unmetered air—bypassing the mass air flow sensor—and then enters straight into the intake manifold. This allows your engine to idle smoothly despite the throttle being fully closed, depriving your engine of fuel.
