I have a JDM B16 in a EJ1 it has a nasty vacuum leak idles at about 2k RPM what is it. Ive had it looked at and noone seems to be able to fix it. Im going to be taking the Skunk2 intake manifold off this weekend. Throw me some ideas.

 

i dont know about a dual cam but with a single slammer that sounds like cruise contol lines could not be plugged up or connected

 

My car has a 3,000 idle right now. I traced it to a leak in the pcv valve breather box. Under my skunk2 manifold.

 

yeah i found mine too i was using the wrong throttle body gasket. problem fixed
