Broken Idle Control Valve connector
So while replacing the fuel breather valve and plugs last night I noticed that the idle control valve hose (big one on the back of the plenum) had cracked. Not sure if due to the previous owner or just plastic fatigue.
The hose is barely in there and I suspect this is what's causing my slightly floppy idle. The rest of the hose looked fine, so before I spend $150 on a new hose wondering if anyone had any ideas. I don't know if there's any easier way to replace just the plastic connector rather than the whole assembly or some other clamp I can't think of. This is the part, you can see how once the outer plastic ring cracks there's only one tooth holding it in. Annoyed I discovered this 2 days after FCP Euro ended their 10% off sale. https://www.ecstuning.com/b-genuine-...e/13417839097/

This shows the busted connector and that it only is hanging in there by a thread and it's own stiffness.

Replace the hose. Fuel breather valve hose must be tight. Bad idle, gas mileage, possible stalls can happen.

The Fuel breather seems fine and I'm pretty sure is routed underneath. I just replaced the fuel breather valve since I had 1 stall since I bought the car, although it was the very first fillup and hadn't happened since then, but it was easy/cheap enough while I was under there. I suspect the leak is causing the bad idle though so hopefully a properly sealing hose will fix that.

I looked through my old service records and saw they recommended the PO do a secondary air pump service at one point, so I'm thinking they must have flipped it while poking around in there.
