Hello JF,

I have finally open my hood 5 weeks later!I have pictures on how to do it..just in case anyone has the same problem.

ok here is my dilemma I found a loose wire coming from some valve by the firewall could anyone tell me where it goes maybe someone could take a look for me on their xjr.

thank you!

 

seems like a vacuum line but to where?

 

looks liket he vacuum line that hooks into a T under the air intake tube. 1 part goes to the intake under the throttle body, the 2nd to the fuel pressure reg and the other part of the T to that line. Common issue for plastic lines to break, just go to auto parts store and match up size

 

where does it connect along the intake tube? will this vacuum line being disconnect would cause any problems?

 

From Brutal's Description, it appears to be this line:

I quickly did this with my camera, so the quality is not so good, but I think you will understand it.

 

I really appreciate that but that particular vacuum is still connected .
The vacuum line I have is about 6 inches shorter .

Thank you please send another video if u can! thx!

 

I'll take off the plastic covers and trace your line in a bit. Then, I'll post a new video or photo showing it's location.

 

You rock man! would this cause anything?..since its not connected!?

This new video shows what it's connected to, but unfortunately, I have no idea what it is, I'm sorry. I will say, that I never like to have an Electrical or Vacuum line disconnected anywhere as I know it will eventually effect 'Something'.

I did turn on my Cruise Control yesterday, and it set the car into Fail Safe Mode, but I assumed it was another vacuum line, or a dirty intake, pcv valve, etc (I had this before)... But, maybe it was this. I'll test drive later to verify.

I'm really embarrassed about how dirty the engine is right now. It's been parked outside, and I've been driving in the Rain/Snow, so it's gotten bad. Oh well, such is life for now.

Also, for future people searching, you might change the title of this thread to "Loose Vacuum Line, Where does it go?" just so it's easier for them to find.

Now, if I've somehow missed the correct Vacuum Line twice, let me know and I will look again. Good Luck!

EDIT: Cruise Control now Works, so I guess this line was the problem.
