    Hi rockitman187.Well, the other day someone told me it's called the crankcase vent tube but I can't locate it at parts stores anywhere.It's the part that the pcv valve goes in to.That's leaking and needs to be replaced.And that might have something to do with the erratic idle.Mostly it revs up a little.What do you think?

    AND to joecoolvette,I checked out . It's o.k., I suppose but I already have the clymer type manual-it's around here somewhere...Maybe if I just take it off and go in to O'reillys or Auto Zone they may be able to match it up.And just to take it off and look at it will tell me more about it.Thanks again everybody.Dave.

    The part that is leaking is the elbow on the end of the pcv tube. You will not be able to buy this at a parts store, you'll have to buy the whole tube from Ford. A common cure for this since it is such a common problem, is to get a silicone angled boot off an old spark plug wire and just swap it out for the deteriorated rubber one that's on there. If you don't have an old plug wire, drive by any busy auto repair shop, most will have something laying around they would be happy to give you.
    This is a major vacuum leak and will definitely be the cause of your erratic idle

If you are talking about the bottom piece,It's called the oil separator assembly.
The top piece is called the PCV tube assembly. I'll include a picture.

    I see! By schematics I thought you meant wiring diagrams! Had I
    known you wanted a pictorial drawing, of every part made by Ford for
    your vehicle, I would have answered differently.

    I suggest you remove it, as you stated, then take it to your nearest
    Ford dealership, Parts Department.

    Yes, a vacuum leak will raise the idle up, and mess up what the sensors
    read. Erratic idle will be just one of the symptoms. Poor gas mileage,
    is another one.

Where can I find a wiring schematic for the rear lights of my truck?

Morning Al Robinson

Sorry about the previous answer... (evidently a PEDDLER spamming our site... to sell MANUALS).

If you want FREE information... go to the BBB Industries site
has "popular" AMERICAN vehicles... (good drawings)... and technical Service bulletins...

Use year 2015... (2016 is not yet available)

The site requires USERs to register (because of "End User Service Agreements (EULA))... but BBB Industries is a
reputable manufacturer and EULA are quite standard when dealing in proprietary information..

If you are going to keep & work on your vehicle... The truly EASY-WAY is to buy the real... CD (cheap) &/or Paper = ($$$$)
- (particularly volume 3 electrical)... Look on eBay..

I bought mine from the DEALER (three books (really great)).

Happy hunting.

Autozone also says THEY HAVE "safety" circuit drawings...
but their coverage is about as sketchy as their parts availability.

2001 Pontiac Montana, is there a wiring Diagram/Schematic to be found?

At a repair shop on a data base, they have the same
info you can buy, if you purchase factory manuals

Free seldom is of much use & the Haynes & others are
next to useless & too generic

Could try auto zone site for free or pay for their alldata
for one vehicle, for one year,that is cheap

2005 crown vic, head light lamps go off while driving, have to pull the turn signal lever to me until the brights come on then the lights go back to normal. If i push it forward the brights do not come on....

It's actually a relay inside the LCM. I opened mine and replace all four for $16 total. You have to be able to solder the leads to a printed wiring board. Not hard if you can solder. Fixed mine...
