AC On, Idles Fine. AC Off, Idle Surges. WTF!

I'm stumped here man. This is annoying. I have to drive with my AC on. The car idles at about 950 rpms with the AC on but once I turn it off the idles surges up to 1600rpms and then drops down and keeps doing it.

Both of my 95 GSXs do this, well after I'm finished using the AC the idle is higher than normal, after a few minutes driving/revving it here and there, it goes back to normal.

Does it surge though?

Also, guys I noticed something today (don't wanna start a new thread). Today I changed out all the vac hoses with some red silicone hoses for the "bling effect".
So, while the car was idling I noticed that my BOV line that goes to the IM was collapsed and also the PVC line that goes to IM. Whenever I revved the motor it would straighten out though and look normal but then get collapsed (as if sucking air) again when I stopped revving the motor. Is this normal?

Edit: For the BOV line the hose was only collapsed on the part of the hose closest to the IM.
