I wonder what the small hose did? Something linked to emmisions / breather system I imagine?...or recirc but surely too small for that?
Its been a while now, I must look in the engine bay to remember what it was connected to. I did leave the small hose on it but not connected at the other end at first. What ever it was, it being off has not had any negative effect as the car goes really well.
