I was looking under my hood today and found these 3 things that were either plugged or not conected. Could someone please inform me of what these parts are or do? Where they should be connected. Is it ok to run like this?

Heres a pic of a tube that I found that isnt connected to anything. It just sits there. I circled where the tube begins (green) and where it ends (red).



Another thing I found was on top of my throttle body there is a piece that looks that there would be a hose ran to. And I also found a hose plugged off. They are bother circled in red.

 

They are part of the pcv system, mainly for emission use. Don't worry about having them plugged.

 

All 3 items? So it wont effect anything on the motor? As far as gas mileage, performance
ect?

 

its perfectly fine....wen i bought my gsr they were plugge. i actually think it runs alot better with out it. i have no idle surge or anything wrong with my vacuum pressure......so basically ur all ok u dont nee to worry about it. its an EVAP system to reduce the amount of unburned fuel into the air.

 

after lookin at those pics.....be sure to plugg up the throttle body port.
