Thanks for the confirmation and explaining that to me!

 

Hmmm, I'll check the filter itself. The box said F20011, but people have been known to swap stuff.

 

Ok, so I am really confused now. I disconnected the W/M kit and just tried starting the engine. I STILL get misfires in cylinders 2,3, and 6. It's consistant now and will not go away. I plugged the tubing going to the nozzles as well just so it was not sucking in any extra air or anything and it still does it. Whats the deal? Oh and my brakes don't work anymore ever since I have been getting the misfire problems. This is starting to make me mad. I did replace the spark plugs yesterday but I have done that a hundred times and never have had this problem. I put NGK BKR7E's in gapped to .028. I also have the GIAC-X ECU installed. Anyone have any ideas? Oh and I took the check valve apart again and it's fine. THere was NOTHING in there.

how about you take some pics on where u have your nozzles....and also how fresh are your coilpacks?

 

F20011 is what is printed on the filter, too.

 

Pictures are uploading now.

As for the coilpacks I am not sure. I just got the car a little while ago. It has 76K miles on it.

Oh and the cylinders that are misfiring are 2,3, and 6. These cylinders are the ones farthest away from the TB. So IDK! [:@]

I see what you mean by the check valve getting in backwards. The single kits have one end threaded.

The firing order is 1-4-3-6-2-5. If 3-6-2 are misfiring, you should really notice it. It still sounds like some kind of vacuum leak. Are you sure where you tapped and installed the nozles are completely sealed?

 

I defenently know there is a misfire. It' idles insanely rough and sounds like crap. I know they are all sealed. I check them multiple times. But would a little extra air going into the intake cause 3 cylinders to misfire? I disconnected the WM kit so NO fluid was being injected (unplugged the hose going from the check valve to the Y splitter thing). Nothing changed. I could plug that hose going to the nozzles and nothing would change. I am thinking it might be something not related to the WM kit. I have no idea though.

gosh i thought our engines were a bitch to work on...that thing must suck lol anyways...idk about anybody else but i cant clearly see where those nozzles are....if you took a shot of the engine bay further away and then photoshopped where they are...it would really help me....im not very familiar with the 2.7T but i can get a better idea...like in the very last pic what is that> to me it doesnt look like a TB ...where are you injecting?
