I popped the hood of my pony to make sure my new power steering lines were not leaking. After a 5 minute look at the motor, I see at the TB there is a spot for a line to fit over at the very top of the TB pointing to the front of the car but its plugged. Down by the fuel rail their is a normal rubber line that sticks up that is also plugged. I asked a friend and he said that its ment for coolant to run through the TB to help shut of the choke mode and if its not hooked up it will make the car run funny in some cases. So my question is, is this line really needed? and if so where is the return on the TB?

Careful not to mix the TB port used for the crankcase evac with the EGR spacer cooling lines (2). This picturehttp://www.veryuseful.com/mustang/tech/engine/images/TPS_IAB_Pic.jpg should show their location.

The two lines on the same spacer the EGR is on are the coolant lines. The one port right beside the TPS and above the IAC valve is the crankcase vacuum port.

so i assume that vacuum is needed?
