Using open wai on the Vulcan I'm getting a burbling sound at idle I can definetly tell it's comic from the intake and I remember my last tec did it every so often but the Vulcan does it all the time at idle, everything else is normal no cels any ideas what this is? Goes away as soon as I touch the gas...

Could probably be your IAC opening and closing. Since it's not a stepper control, it opens and closes thousands of times per second.

Actually 40 times per second.
