Need some help

I installed a fpr and had to take out the intake manifold to make space, and this breather hose got disconnected and i do not know where the end connects to. I looked everywhere couldn't find the connecting end. And now, since I didn't connect the breather hose completely, the car starts idles a bit and stalls. Here is the picture of location where breather hose is:

the breather hose is underneath this part that i circled, so my question is where the heck does the end go?

The breather hose is too short, god damn I'm thinking someone tampered with my car when I put it outside for a long time. Anybody have a e30 like mine I need to look under your hood, no homo.

I don't get it, this breather hose did not connect to the intake boot to begin with. It is just too short. And the intake boot is plugged with a cap of some sort.

picture of mysterious hose problem

here is a picture of the intake boot, you can see that there is a hose already attached to it. And there is a cap plugged under where the white circle is, and the picture of the hose that connects to the ICV is short it cannot reach. So where does this hose go? I don't know it is a mystery to me.

This should explain things better.

#11 goes to the upper intake manifold and #17 goes to the intake boot beside the air flow sensor.

need some help

I bought a new air hose and installed it to the icv and connected it to the intake boot. However, when I start the car it does the same thing, idles a bit, then stalls. I checked all the vaccuum lines and they are all connected. I checked the icv to see it was connected, but the car still stalls. What did I miss? The last thing I worked on was the fpr, had to take off the intake manifold to make space thats when the air hose got disconnected from the icv. Just for the record, the intake boot was plugged with a cap and the air hose is too short so i made an extension and took off the cap and put the air hose in there. My car is 1991 bmw 318i M42 engine.

here is a picture of what i did:

You see, now there is two air hoses connecting to the intake, before it was just one. I'm lost on this situation someone help me.

That hose looks like it connects the intake boot to the icv.

That is exactly what I did, but before the intake had a cap plugged in it and the air hose could not reach the intake boot, so I used an extension hose to connect it and it has surging idle then stalls out when I go start it up. I don't know what I did wrong. I checked all the connections. The last thing I worked on was replacing the fpr, and I had to take off the intake manifold to make space. Then somehow the air hose for icv appeared and I didn't know where to connect it. But later I read on this forum, so I installed the hose connecting to the icv to the intake boot and it still stalls out. I'm lost what did I do wrong?

Does the rpm jump up and down before it stalls?
