High Idle

So my car started idling really weird above 1-2k, here is the video of that

After that i took someones advice and playes with the idle screw and made it idle at around 800-900, but now like when i rev it, it goes down to 1k, then goes up to 1.5k and drops down to 800-900 heres a video, anyone have any idea wut i should do ?

Put the idle screw back to where you had it. That wasn't your problem. By adjusting the idle screw you are merely masking another problem. You likely have a vacuum leak somewhere. Try cleaning your throttle bodies as well.

That's at WOT. It's lower at idle, but I can't recall exactly.

Might I suggest Rizz's link page.

If it just started doing it, then I'm guessing vacuum leak.
