Vaccuum tree diagram

[drhoward]

Hey I just picked up my 1993 Explorer and after looking around the engine bay for a while I noticed that there were a couple of lines disconected from that vacum tree on the intake manifold (causing it to idle pretty high too)

Does anyone have a diagram of where they all go? I need to pick up a manul for it one of these days but I figured I would ask on here first, someone might have a link or something

Any help would be appreciated

Cheers
Kev

look at your core support it should be in the middle by your hood latch potentially buried in dirt and grease

Fortunately, there isn't too many. Trace each disconnected vacuum hose to its origin, and post back. Oftentimes, I see the cruise control disconnected [unit is on driver's side near firewall] for some reason.

Ya I looked around for a while trying to find a disconected line else where, but didn't have any luck


It will be nice to bring the idle down to less than 1500 rpms, I can cruise along at 40 kph with my foot completly off the pedal, lol

a couple of them (2 i think) are usually just capped off

That would make sense then, I think I am just going to cap them off for the time being to get the idle down

Next weekend I am planning on doing a major tune up on it (plugs, wires, fluids,filters etc) it doesn't look like the previous owner did all that much mainteneance on it.....she was pretty dumb so I really doubt anything was done actually lol

I just double checked, I have 2 capped off. I was having a problem with the transmission vacuum modulator. Its a common problem that causes transmission fluid to get sucked into the tree and blows off the lines and caps. Hopefully thats not why your missing some caps. That is a pain of a job.

I'm not sure why they were missing, I just bought the thing hopefully its nothing major
