In the picture there is a vacuum line that is capped. I am wondering what it is for. It is the small line in the center of the picture just above the PCV valve and below the yellow ty-rap. My Truck is a 06 STX 4.6 Auto. Thanks!

That vacuum line in question looks like it's for the IWE (locking hubs). Where does it start from, back of the intake?

Darkus Mingler

I can't tell it goes into the wrapped bundle that is just behind the hose over it.

Is your truck 4wd?

Darkus Mingler

No it is 2WD.

Is everything working as it should? CEL on? I wouldn't be concerned unless your having drivability issues.

Darkus Mingler

Yes, all is good. I was just wondering.

This question comes up about once a month or so, it is a vacuum line for the 4wd system that your truck does not have. The factory will most of the time install the lines just in case it turns out to be a 4wd truck. Don't worry about it since you say you have a 2wd.
