OK, it's been a while since I posted, but that's kinda good. After my 1991 318iVert's diff ate itself, I finally was able to get it replaced and get her up and running. She's been my daily driver since, with little to no headaches. She's always been a little rough at idle, especially at startup, but it would clear up once I was running and was never that big of a deal.
Until Tuesday. That's when she started feeling off. Idle was REAL rough, tach was up and down, exhaust smelled very strong, and she in general felt like crud. I brought her home, did a little stomp test, and got 1222. After looking that up, I realized it means almost anything could be wrong. Most folks online who'd had this code seemed to trace it back to vac issues, so I started poking around.
Picture 1 is just a simple wasted hose. Easy to replace.
Picture 2 is a weird hose assembly running from underneath the intake boot to underneath the intake manifold. I noticed it was covered in nastyness and rubbed some away. You can see the hoseclamp that got exposed when I did.
Picture 3 is that same hose assembly at one of its junctions. It's wasted and I was able to pull it off with almost no effort.
Picture 4 just shows all of that crap in context with the intake boot out of the way.
Picture 5 is just a clearer picture of the same hose assembly in situ.
So heres my question: What the heck is that thing called? Its has a metal pipe coming in from a hose assembly I believe to be associated with my idle control, air from the intake boot, the branch where the damage was the worst, and a metal pipe coming out the end underneath the manifold. Seriously, what is this thing? Can it be removed without screwing around with those metal pipes? If I find the replacement, should I just cut the existing one off? Any advice?
I've been trying to find it on realoem.com (
