The one with a circle that I blocked.
The hose Teed going to the throttle body also goes at the top hose (with red arrow), eventually on the top of the intake plenum.
Is this a vacuum hose? goes to air pump that I deleted????

Thanks

lotus7racer

anyone???

Had another look at it and believe it's part of the EVAP system. Notice that that hose t's off the iacv line. That's probably why your car is fast idling. I'd bet money that once you plug it the idle will drop.

Can someone take a look at their car and please glance where this hose supposed to go?

that goes to a inlet undernieth your rad. hose right where your hand is go straight under the radiater hose and its right there

lotus7racer

05---oh! bless you and thank you.

So that hose I'm holding goes to the the inlet hose going to the radiator. So that hose is a water line that feed or maybe a return from the throttle body area?
If that is a water hose, why is it going on the top of the plenum (I thought its a vacuum)?

Maybe the reason why my idle is way too high?

I deleted the stock radiator hoses because its a racing car. Probably why I can't find the connection.

Thank you.

Does it run to a metal T ? I still think it's a vacuum line. It looks like the hose that runs to the evap canister solenoid. It pops open and sucks the stored gas vapors out of the canister.

Yeah it has a T at the bottom of the head. I'm confused. O5 said its a water line....you said its a vacuum.

If you look at the picture, one end of the tee goes on the top red arrow) and the hose snake to the top of the plenum (red arrow).
The other end of the T goes to the red arrow again on the throttle body.
Just follow the red starting from my hand.

That is definitely a vac line then.

First off, sorry for the huge pics. They have faint circles in them, so zoom in on them.

It starts here in the red circle (anything circled blue is vac too, fyi):


Runs to this T circled in red:


And eventually down below (red) into this solenoid(blue):


Additionally, I steered you wrong somewhat yesterday. I showed two lines coming out of the IACV and said they where air lines. They are in fact coolant lines to prevent the valve from icing.

They start here at the bleeder screw:


Run into the throttle body(red), to keep it from icing as well, and out (blue) to the iacv:


This is the flow path through the iacv for coolant:


The outlet runs down to a lower part of the coolant system. I may have the flow reversed, but you get the idea. The IACV uses a passage cast into the IM that runs from the throttle body back to the valve, and into the plenum. Sorry for the confusion.

I did not say it was a water line maybe you should read a little closer to my post. I said it looks like it goes under the radiator hose.
