1.8t 20v inlet manifold vacuum hose

When I bought my car (5 door with a 1.8t 20v) one of the things the seller mentioned was a hose that went into the brake servo. It runs from the end of the inlet manifold and then into a hole on the brake servo and he said if it comes out the car goes lumpy so you may want to seal it.
So, today I sealed it up with a bit of blue tack and it made the cars idle drop dramatically and it didn't sound like it was running as nicely. Is this definitely where the pipe should go? And is it best to have it sealed or just in but not sealed? Will having it sealed cause any damage?
Any advice would be great. Thank you!

I don't think there was anything. I think it was just a bit of pipe. What should it look like with a check valve in and why does it need one? Does the pipe have to be sealed into the brake servo?
The check valve is a one way valve i believe which is circular and needs to be in the pipe between the inlet manifold and the servo. I don't think I have got a pic of mine and am not with the car at the moment

The brakes are okay, feel very wooden (race car ish) but not as good as I think they should be now I think about it

Should I just seal the pipe into the brake servo and just leave it like that? Will it learn to run properly after a few minutes? As I can almost guarantee this is what was causing my car to bog under acceleration, as it wasn't sealed in the vacuum it was leaking causing the air fuel mixture to be lean. Plus, it should be sealed and there should be no air leaks.
I just want to know why it didn't seem to run nicely when i sealed it in

By sealing it I am reducing the air intake so the ECU has to learn this and should after a little while run properly again? (once it has learned it does not need as much fuel, as there is now less air)
Please someone say if this sounds correct as I am going home from Uni on Tuesday night and will have a few days with the car. If this is correct I will seal the pipe into the brake servo and hopefully it will learn the new air-fuel ratio required, THENNN hopefully the engine won't lean out under acceleration causing it to hesitate!

Keep your eyes open for a proper servo connector
