Help! Need a Yota Vacum part asap!!

[Ricky B]

Hey,
My buddy needs a part to get his yota running cause it's stuck in the parking lot. Anyway he needs a vacum sensor thing. it's hard to decribe it's small and mounts on top of the engine and has two ports on the front of it and one in the back that all have tubes that run to the other side of the engine. This is an 85 yota 4runner with efi. Autozone doesnt have this part and niether does the junkyard thats waay down western. its the 4 cylinder 22RE motor and we need this asap.
Thanks and i'll try and get a pic of it asap.

Which part do you need ?

 

[Cperry]

i think he is talking about the VSV sensors that are on the valve cover. i doubt if that is why it is not running or starting.

 

[Blkvoodoo]

yeah, I wondered that after I posted the pic

plugging off the lines should make it run, maybe not well, but it should run

I got a pic of the vac schematic for my '90, but the one on the 85 is pretty nasty. If that'll help identify the VSV, hollar

It's actually not any of those in the picture I don't think, it is more towrds the front of the engine. Anyway yea it'll run and start but, when you drive it won't let you get above about 2000 rpm like it's deciding to cutoff the fuel supply or something. So anyway we opened the hood and started looking around and found that the vacum hose thin was broken off. Then we tryed to electrical tape it back together and the truck started running fine again but we didn't make it far down the road b4 the tape lost it's hold. So yea we just need this one small square shaped thing that like I said has two hoses ports on the front and one on the back and it says vacum on it and has a bunch of numbers I'm gonna try and go get a pic.

Yea here are some pics looked at that link and that seems to be what he need a VSV thingy. Anyway I still need one and the local junkyard didn't have any, so anyone got one of these?????

I saw he got his from a 3.0 V6, only thing is the one my friends has has another vacume line coming out the back of his sensor instead of that black cylinder thing. Here's some pics below and I can take more if neccesary.

I've got a efi parts rig up here in the Franklinton area. Come get the piece. PM me for my number.

 

[Ricky B]

Pm'd ya Ratman

Oh and here's a pic of the sensor in the daylight:

 

[Ricky B]

Still need this part!!!!! Ratman hasn't pm'd me back yet, anyone have one or a parts yota, etc, etc??????

Plug the line, drive the truck, all that VSV does is idle the engine up when the AC is on.

If you would have read the link I posted, you would have known that.

Hmmm I must have missed that when I read it but we already tried to plug ti up and drive it and it still does the same thing:

When he drives it he can get up to about 2/3 grand then all of a sudden the engine starts to die as if it is no longer getting its fuel supply.

So if that not what a VSV would do to the engine than what is it that were dealing with, anyone know?
Thanks

ok, there may be some vac line issues as well.

Follow the lines, those lines should go to a vacuum daiaphram on the side of the intake, but they may have been routed to the Fuel Pressure Regulator ( back of engine, single diaphragm, one nipple) Unplug and cap this vacuum line ( allows full fuel pressure all the time, mine has been disconnected for quite awhile)

If this doesn't fix the problem, or at least change it, he may actually have another issue.

ok the two lines on the front of the vsv run to the side of the intake manifold, then the rear line off the vsv runs to the back of the intake manifold is that what your talking about plugging off, where that line runs to the back of the manifold?

 

[Blkvoodoo]

is there a diagram like this under the hood ?

Don't use this one, it is for my '90, has a few more "features" than the '85

Mine isn't picworthy, or I'd post it for you.

Fuel pressure regulator is mounted on the back end of the fuel rail, near the firewall, single vacuum line to it, pull the vac line, and plug it, then start it and see what happens.

just plugging the vac line at this VSV should have no effect on anything other than idle when the AC is on. The BLUE colored VSV further back 'could' have an effect if lines are not correctly routed.

Check it out

Thanks for all the info man, we'll try it and see if it works.
