Please help with fault codes

I am getting next codes:

2A70 - which showed VVT
2CA2 - which is lambda o2 sensor
2CA3 - which is lambda o2 sensor
29CC - which showed misfire several cylinders
29CF - which shows misfire cylinder 3

I got no idea where should I start with troubleshooting, I'd appreciate if anyone can point me in right direction.

I also have question, this issue comes on N46B20 engine (E90 318i), now I am wondering would it cheaper if I just replace the engine with one more powerful (3.0 or 3.5i)?
Appreciate 0
