Video - Help! Is this IMS? What's up with this engine?

The idle bounce could be a number of things but I would get the throttle body cleaned first then test for vacuum leaks.

The rattle could just be chain tensioners.

I have no direct experience with IMS bearing failure but you will have a significant leak on the underside of the motor, then at some later point in time there will be nasty grinding sound just before the motor chews itself to pieces.

I agree with vac leak / dirty throttle body.

I had exactly the same issue. I had the wrong MAF sensor in my car. I replaced it with the correct one and it has been fine ever since. I was able to sell the "wrong" one along since there was nothing wrong with it other than the fact that it didnt match my car.

Do this. Check the part number on the MAF sensor in your car. Use the year model and VIN on your car to select the correct MAF sensor.

There are a LOT of articles on the web about this.
