    but i dont know the answer and i work with frickn cars!
    there is a hose, runs from the intake tube (just before the throttle body)
    to the back side of the driver side valve cover.

    what is it, what does it do?

    mine keeps coming out of the valve cover and makes it run shitty.

    thanks guy.

    I'm gonna say it's either a crankcase vent or a vac line. Removing a vacuum line would make it idle really crappy but I don't know why one would run into the crankcase.

    probably the breather hose that runs to the PCV valve.
