Default Need some quick HELP!! Throttle Body ???

I am putting everything back togther after removing my heads.

On the passenger side of the throttle body, there is the hose that goes to the valve cover. Under that, there is a hose that goes to some solenoid, and then the hose comes out of this solenoid. I am lost at where that hoes goes. For reference, there is another hose under this one, and that is the coolant hose for the throttle body.

This is the last peice of the puzzle, please help. Want to start her up tonight.

I don't know for sure regarding a 94, but they both make their way back to the manifold, I think...

I will have to check the helms manual, tho....

One for sure comes out the TB and into the solenoid. I have looked all over and at this point, can't find for the life of me.

Searched all over the web, no pictures anywhere.

My Haynes manual is not help either.

I, too, don't know about a 94, but the hose coming out of the solenoid should be vacuum and should tie in to a vacuum port, EGR, cruise control, gas tank vent or a 'T' somewhere. Probably buried where it's hard to see.

Default Hose goes where?

Here's a picture of mine before I molested anything. The vacuum hose makes its way back under the coolant tank, joins a plastic hose and goes through the firewall. I'll post a picture of that when I get them uploaded.



I'll be back.

OK, here's two current views. The other hose from the relay goes over under the air conditioner hoses toward the washer fluid fill.



Here is a picture of where it joins the plastic hose, it's right above the four relays in this picture.



Hope this helps. Is this hose to vent the charcoal canister or the fuel tank? I don't actually see it going through the firewall, it must go under the car to the back.

Sweet, those pics helped. That plastic hose had fallen and was laying flat. That is why I couldn't see it, plus I didn't take a picture of that before removing it. I had taken a picture of everything else.

Thanks a bunch!!
