'07 RS4 - did carbon cleaning, now idling horribly - pictures of vac hose routing?
 

Hello! I bought my dream car in November (a Mugello Blue B7 RS4) and have been loving it. I eventually had intake manifold runner flap issues and took the intake manifold off to troubleshoot those and do a carbon clean. Got it done and all back together only to have it idling roughly and throwing random/multiple missfire codes on cylinders 1-2-7-8 (which I believe is the entire ECU #2 portion of the engine). I am not sure I got it all back together right. When I checked it out when it was running, I discovered a lot of suction at the highest horizontal port on the "mouth" of the intake manifold, which is open. It doesn't appear anything came from there, but I've learned my lesson to mark my connections when disassembling. Can someone please take a few shots of the vacuum hose routing around the intake manifold on their WORKING RS4 so I can verify I have everything right? Here's the port that's open, but I honestly have no idea what might be mixed up. Any and all help will be tremendously appreciated. Thank you!!!!!!!!!

I should have mentioned that covering the open port with my finger smoothed out the idle, but when I plugged it permanently and tried higher RPMs, the engine almost totally cut out at around 3k RPMs. I have used an inspection camera to check all of the vacuum fittings under and around the IM and it appears they are all in place.
