2007 c280 idles rough

I have a 2007 c280 benz. Off and on it would idle rough and it was fixed when i turned off and on the car but for 3 days now it doesnt fix the issue. Took car to have codes read and i was told ignition coil number 1 was having issues so i replaced and became worst then i changed spark plugs today and no fix. I also cleaned the airflow and no fix. I have all these codes that have been coming back
P031 single cylinder missfire #1
P0020 intake camshaft position actuator open bank 2
P0017 crankshaft position bank 1 sensor B
P0351 ignition coil A primary/secondary circuit

What should i replace next?

Need help with the rough idle.
