In working on a rough idle situation, I've taken out the idle control valve and cleaned it. Now that it's clean, I can see it has a "direction" arrow. Anyone know which way it's supposed to point? Toward the engine or the throttle body?

Also, any hints on replacing that same idle control hose that winds under the manifold and connects closer to the engine? I have a new hose in hand, but it looks like a bugger to get to.

Thanks!
