Hello skottie.
I have a honda civic ej9 97'
D14a3 with 1.6 admision.
My problem is the idle rpm.
When engine is cold , starts up with 2500 rpm , and slowly descercase when engine get warm
When get the working temp . Stay around 1000 rpm . , it's normaly ?
(It.s second hand car from Belgia)

I'd look for vacuum leaks and try this video of Scotty's that shows how to clean the throttle body:

I cleaned the tbrittle and IAC valve and same I forget to say. :(
