Makes sense, but in my case it didn't do a difference even though the bolts were very loose.

I'm so extremely busy with work at the moment that i didn't have time to properly read the pictures until now. Realized that the instructions don't include drilling a hole to the metal bits of the AFM, just removing the plastic plug haha. Because of that i thought it was somekind of hack. The procedure seems simple enough but i have to take the car to a local porsche mechanic because i don't have the gas test devices.
Well yesterday was as wet as it can get when i left work before midnight and the car ran perfectly so now i'm even more bafled...Also i have diagnosed that the misfire goes away when i "wake up" the engine by accelerating hard over 4k rpm. It would probably go away instantly after start if i'd accelerate, but don't wanna stress the cold engine. And the worst misfire happens in cylinders 6 and 2 (the old plugs in those weren't only carbon fouled, but also a bit oily).
