All cylinders misfiring, after checking coils and sparks

Hi All,



I got a 325ci with the CEL light on a few weeks ago. Ordered a OBD2 and it got here now, read all the p0300-p03006 codes.



Plus a few others. see pic.



What can be the problem? I checked intake boot and it looks fine, changed all spark plugs and still the same codes. I did the coil exchange check and they all look fine. whats next?
