so my car idles at around either 500 or 800 rpm, no in betweens. it switches periodically, and each time there is a prominent click. it sounds like it's from around the intake manifold, but i don't have the best ear. i might link a video tomorrow if i'm not lazy. is it possible the icv is sticky, and that's causing the periodic click? i cleaned it out pretty recently, would it be wise to take it out and give it another clean? or is there any other suggestions? the starts are also a little jumpy, but succeed every time. it's really not obstructive or anything, and i kind of believe in the "if it works don't fix it" mindset, but it'd be real nice to have a smoother idle if it's a cheap fix. thanks!

Sound like you idle valve is sticking. It can click if it opens or closes.
