need help on b16a J-Spec ideling

I have a 1991 CRX with a b16a J-spec engine and an integra type-r tranny....my engine idels at about 1500-2000 RPM instead of the usual 600-900 on most cars. I dont know if this is a normal thing with the b16a or what but it wastes my gas and puts wear-and-tear on my engine so if anyone knows anything about this please let me know. And also if anyone knows where the idel screw is, I found 2 possibilities but both are tightened so tight i dont think theyre it. Thanks

unhook your throttle cable, does the rev drop ?
you can also adjust your idle screw.
you might have a vacum leak or the vacum hoses are not hooked up properly.

alrite, I'll check those out as soon as i have a chance, thanks
