The D14A4 engine I have in my civic is completely stock, not any engine mods at all.

I've done abit of looking on the net and it seems that its more than likey a faulty IACV, but trying to find one at a reasonable price is hard.

No I don't mean 2000-3000, I mean 200-300, it is idling very low

I haven't replaced the TB or IM gasket as I haven't taken them off.

When I start my civic, from cold it idle's at about 200-300rpm then once its warm it idles at about 950-1000rpm.

Is this a IACV problem or something else?

I've taken the IACV off and taken it apart (as best you can) and cleaned it with carb cleaner but its still the same
