Hey guys just did a 96 spec b18 type r swap on my 93 cx hatch and im wondering where to hook up this vacuum line to (the one that's on the back next to the IAC valve) I have all my lines hooks up. When I got the motor is was plugged. Reason why I ask is cause I'm having a bit of idle issues where my RPM's would fluctuate and then go back to normal. Already checked for air inside cooling system and I have a new IACV
