PLEASE HELP with hanging idle!!!!

[BillyBob]

I noticed that with the temps going up that my cobra has been really slow at coming back down to idle. sometimes it stays around 1200 rpms and if i rev it up. it normally comes back down to around 800. if it annoys me too much i just pull over and shut it off then restart it which it is then fine. What I am wondering is.. Does anyone know why it does this with the changes in the weather? and any ideas on what to replace or what to do.

the idle control valve might be sticking due to the heat or gunked up a little. you can also adjust the idle coming down within the tune. My 2V does this a little still where you rev it and it kinda hangs for a second before falling. also make sure you cable is well lubed so that it doesn't bind or hang up any
