Default Please help, Dont know what to try anymore

Hey guys im new here, and not much of a car expert. I have an audi A4 b7 2.0, my Ac is stuck on econ mode, and when I accelerate rapidly the engine sort of punches. I already tried Changing the Intake manifold, Thermostat, Diverter valve, And the Mass airflow sensor. Nothing seems to be working. Also the car gives me low RPM when driving so it burns through gas Pretty fast
Here are the codes:
Cylinder 1,2,3,4 misfire detected
P12A2: No DTC definition found. See service manual
P0172: Bank 1 System Too Rich
P0299: Turbocharger/supercharger A underboost condition
Any Advice would help. Thank You.
