Some logs from JB4
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. https://drive.google.com/file/d/0B5b...ew?usp=sharing Second link car remained in limp mode while I cruised a bit. https://drive.google.com/file/d/0B5b...ew?usp=sharing Third link no limp mode then into limp mode cleared code to remove limp mode continued driving until limp came on again. https://drive.google.com/file/d/0B5b...ew?usp=sharing

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.
