Some logs from JB4

[sjd6795]

Engine is in a constant limp mode now(engine malfunction). I was able to clear codes and to continue driving. Car sounded like it had a missfire now it's clear it's running on maybe 3 cylinders. I have new plugs and coils coming in tuesday. I really hope that resolves the issue and it isn't a fuel issue even though the logs show weird AFR readings.

Could it possibly be my o2 sensors going bad or maybe the vanos?

First link car was cold ran fine obvious missfire can be heard no issue with limp mode.

Second link car remained in limp mode while I cruised a bit.

Got my plugs and coils pulled out. cylinder 4 and 5 had a lot of metal shavings in them. Several plugs looking black and the coils had a lot of rust and black. Some looked good still as well as cylinder 1 and 2 plugs.

New coils/plugs needed? Might as well change everything out. Mostly the coils. But I'm no expert.

Yea I just put in some new spark plugs and issue is still there my coils come in the mail tomorrow I will put those on and see what happens. I have a feeling it could be carbon build up on the valves but who knows. A few months ago I had the car into dealer for a long crank and eventually wouldn't even start once the engine was warmed up, once it cooled off it would start again.

They ended up replacing 2 injectors, a faulty valvetronic motor, valve cover gasket and other actuators and decoupling elements, gasket rings etc..

I'm getting codes
P0300 to many random missfires
P0301 missfire cyl 1
P0303 missfire cyl 3
P0304 missfire cyl 4
P0305 missfire cyl 5
