Hello I just did a B16A engine swap in my 2000 DX and it has a wierd idle issue.
On the intake manifold there are the two vacume hoses the bigger one and the smaller one. I dont know where to hook the smaller one to. Im guessing it has something to do with the idle. Any help would be awesome.

Is it just open or did you plug the hole somehow? An open vac leak is a sure cause of idle problems. If its plugged and just maybe not hooked to something, I don't have the slightest clue.

Thanks any way. I found a Vacuum Hose diagram. The opening is pluged but it goes to a peice under the MAP sensor Im gonna try that and then do the timeimg on the car. Should be good I had the same problem like 4 years ago when I helped do a swap in my buddies Civic DX. I'll let you know how it goes.
