Vacuum Leak?

[sugoie]

I did a burnout in my 2011 mk6 gti because i have new wheels to put on it, anyways it threw up an epc light and is misfiring through the entire rpm range and has absolutely no power. I had a very similar issue when i first got it and it ended up being a simple vacuum leak and i used a code reader at the auto store on it both times and the codes are almost all the same. I have a picture attached with the codes. I used starting fluid to check for vac leaks but couldn’t find any. any help is appreciated. Thanks in advance

Also i put a catless downpipe on it months ago but i have never had an issue with it other than the cel on, wanted to do a few more upgrades before a tune to clear all of it up
