90 crx si b16 idling problems

So yesterday I went and bought a 90 crx Si with a B16 swap and a few aftermarket goodies, but when it idles, it either idles high or bounces from 1k to 1,500 rpms. any idea's on what the problem could be?

I am fairly new to honda's so I am not sure what a IACV is. Also someone told me my O2 sensor might be going out, but I really have no idea.

Re: 90 crx si b16 idling problems

does this happen only when you start it, or does it happen after it is warmed up as well?

Pretty much all the time, sometimes it will stay at about 1,600rpms but eventually the rpms start bouncing again I dislike it very much.
