Re: Vacuum leak questions
You might need to buy about 10 feet of vacuum line & just replace all the vacuum lines in the area. The next resort is to get one of these mechanics stethescopes & pull the metal part off to listen to where the leak is at. Most auto parts stores sell them.

Re: Vacuum leak questions
also, spray some carb or brake cleaner around the vaccum lines, when the idle fluctuates, you found the leak.
Try that first.. I must have been a little buzzed on previous post.
Re: Vacuum leak questions
I agree with what 88Accord-DX said. Usually if you use the carb cleaner method you can find leaks. It might be a very small hole that is very hard to see so replacing all the hoses may be the way to go if not the vacuum removal mod that you mentioned. Also if the actual metal tubes are rusted they may have a hole in them so check those as well.
