Hi guys,

I have a 2008 F150 4.6 Triton. It started idling rough so i went about checking vacuum lines and came across one that was just laying on top of the intake manifold. When I turn on the engine, it has strong suction, but I cannot figure out where it is supposed to be plugged in.

I put it up near the throttle body so you can get a better view of it:



Please help.

Thanks!

Just a guess power brake booster hose.

That is a vent line for the EGR valve, just let it lay where it was.
