This is my first post so here we go!
I have a 1987 Honda Prelude 1.8L dual carb and I am looking for the name of the part that is vacuum line hooks up to. I believe it is a nippodenso part, but it has no label. Also, I was stopped at a stop sign and my idle dropped and the car stalled. It would not start again until I covered the vacuum line and then it idled fine. Could this part be causing an idle issue? I have a picture of the part and highlighted it (it is taped up). I also took a picture of the vacuum diagram and highlight the part I think it is as well.
