Drives fine. Drove it a good 40miles on the highway today nothing bad came up, no check engine light nothing that made me think im in trouble but the car idels up&down on stop (the video shows it going up and down a little n slower but more then 50% it goes from 500-1000rpm down and up) and worse when the A/C is on. you can see it moving and the car shakes a bit thats not me moving the camara. everything seems fine with mine eyes. My best gues would be a vacum leak?...What you experts think? thanks for any information

you don't have the F/IC installed do you? If so, should be an easy fix...if not, may be a few different things.
one thing is to try to 'flip' the spacer on the throttle body - make sure it is facing the way it says in the service manual. the little tab that sticks up on the plastic piece between the TB and the Intake Manifold is suppose to be going a certain way. in the factory some of them were put on wrong. there are several threads about this, but are hard to find b/d they don't reference this issue in the title, I don't think. either way, might be something to try. I flipped mine and it works hella better now.

From the video the idle looks fine to me. Maybe a vac leak or the the throttle body gasket like Joey said.

The vibrations are coming from the car during a rough idle, but shouldn't be that damn bad if you have the stock rubber mounts.

Do you have an aftermarket intake? Is everything tight and hooked up? My intake tube popped off one time after heavy driving and the MAF sensor was getting a bad reading causing it to idle up and down. The car actually stalled out one time as well. I hooked everything back up and made sure it was tight. Problem went away. So my advice would be to check out anywhere on your car where air is being pulled into the engine. Like the others said, check the TB gasket out as well. Hope this helps.
