Code 30FF and no boost

[e82bro]

Hey there I had been fixing a misfire on my N54, I took out spark plugs, cleaned them up and also regapped them. I took my car out to test whether I had fixed the problem because it was still misfiring under throttle. Then BOOM, as soon as I left my driveway limp mode and code 30FF (I had protool open) popped up and pulled over. Since then it’s running with no psi or anything?

Where abouts shall I start? Would 30FF be in any correlation to the misfire? Would I have knocked off some vacuum lines in the process of taking out plugs or putting my engine cover back on?

I would get a smoke test done to see if there's a leak somewhere. Could be the valve cover.

Vacuum lines were loose, all it took was clearing codes and it was sweet, I’m just dealing with misfires now :/

VCG might need replacement as oil was in coils 2&3

You said you had spilled oil during an oil change, right? I had the same issue you're dealing with and it turned out to be my valve cover. Go get that smoke test to rule out the valve cover is my advice. Good luck.

Sorry for the noob question but would this cause misfires? I’m misfiring on cylinders 1&2 and throws check engine light, it’s not driveable for more then a kilometre then it will misfire

Quite shocked is an understatement when I took my injector bracket off and they just popped straight out
