Whining noise when I left off throttle
So I recently took my aftermarket intake off and put stock back on. Now I have a whining noise coming from the diverted area it sounds and my car is studdering really bad. Who knew this would happen when putting a stock piece on???
Anyone experience anything similar to this?

I was pulling the inlet pipe that the intake goes into because it wasn't high enough is it possible that did something?

You could have created a vacuum leak. Any unmetered air coming in after the MAF is going to throw everything out of whack. The area from intake to turbo is always under vacuum.

I just realized that the piece that connects to the inlet and up top by the oil came off the pipe...

Does it just go back on? I pushed it on and it didn't seem to do anything and I saw there's a screw next to it

You are talking about the PCV hose right? I know on the valve cover side there is a clip with 3-4 prongs that hold it on, but i am not sure about the other side that goes to the inlet... i honestly thought it was not removable from that side but i could be wrong. When i did a boost leak test i disconnected from the valve cover side.

UPDATE**
So the hose connects into the inlet, that piece broke so I now need a new inlet

This is what i thought in my other post; its permanently attached to the inlet and only the valve cover side can be disconnected. Sorry to hear that. Let us know the part # and cost for the inlet if you can, i'm sure someone else will need it eventually.
