Oh man. It happened to me but I don't know the exact way of telling/showing you what to disconnect on the car.
There is a small hose running along the back of the intake manifold between the actually manifold and the firewall connecting to a larger hose (small one coming from the right, larger one from the left). In my situation (exactly the same thing you are saying is happening) there are two hoses ( I think EVAP lines) that were connected together (one bigger going into one smaller) so what I did was disconnect the two lines and insert bolts into the holes that were about the same size and then used a zip tie/bracket to make sure there was a good seal between the hose and bolt. Do this on both ends and you problem should be fixed.
Man I hope that helps but I know it's just words, shit if I only had a digicam to show you a picture of what I did. IM me if anything or e-mail.
