So the other day there was a misfire on cylinder 3, a day after adding some Chevron fuel system cleaner. The day after that I bought new Bosch plugs and figured I'd put new ones in there. After everything was installed there showed a misfire on cylinder 1, 2 and 3. I already swapped coil packs around, and just added different injectors in cylinder 1-3 with the same issues. I'd also like to note when changing the plugs on cylinder 2 and 3 there was some liquid in the spark plug chamber. Anyone have any clue what this could be?

EDIT: just pulled a 30BA code via INPA. This is a 2007 335i E90
