Default Replace just ignition coils ???

2008 audi A6 3.2 quatrro with over 210K miles suddenly just started with LOUD ticking sound. Initially thought it was the timing chain tensioner that needed replacing.....BUT.

After adding some seafoam to nasty old oil, changing the oil......the engine started VERY roughly. In order to keep the car running you have to step on gas. Drove it this morning and NO power at all.

Got these codes this morning:

Audi Codes

PO300- random/multiple cylinder misfire

PO068-mass airflow sensor, throttle position sensor and the Manifold pressure (MAP) sensor.

P12A1- Fuel rail pressure sensor-signal low

P0346-camshaft position sensor A circuit range/performance (bank 2)

P0172- Fuel trim, bank1 system too rich

P0301-cylinder 1 misfire

P0302-cylinder 2 misfire

P0391-camshaft position sensor B circuit range/performance (bank 2 )

P0306- cylinder 6 misfire

P0305-cylinder 5 misfire

Should I just replace ALL the coils and clean air intakes or MAP?

Thank you in advance for any advice/help
