Can anyone identify this hose

Hello again,

Does that hose have vacuum leaking wen it runs?

Roy

I hadn't checked that but i will. I only looked for fluids.

Okay, it could be the hose for the PCV valve or the hose for the emission canister at the back of the car.

I do not have a vacuum diagram but look around for the other part of the hose.

The second third and forth pictures are of the other end. Actually i found a better picture of the hose before i went ahead and took off the other half. This should help.
I'm unable to put my hand there with the engine running and the other lines connected but i can definitely hear hissing and the idle level jumps up and down.
I also get a thud like sound which i have heard before i change the idle control valve months ago.

I'm looking at this picture which i took this morning, i noticed the hose with the white fitting was disconnected so i assumed it attached to the metal tube below the throttle body because it had nothing connected to it.
Comparing the pics i see the broken off piece is supposed to attach to the hose with the white connector on the end.

The first picture looks correct. The second picture looks like a water line and the hose is not the hose you have in the picture.

Roy

Yes, yes the first picture is from when it first happened the second picture is after I had taken the broken piece off and was reassembling and notice that that metal piece did not have any connection to it. so I assumed that the white coupling piece went there but it doesn't.

I just found this online and it looks like both lines from under the throttle body connects to the one hose with the white collector on the end of it.
