Need help with Audi A4 2000 1.8t Misfiring and Fuel/Air Problems?

I was driving down the highway when I noticed my car was misfiring and my car started to smoke. The CEL started flashing then stopped after awhile. I checked the codes and this is what I got:
P0300 - Random/Multiple Cylinder Misfire Detected
P0301 - Cylinder 1 Misfire Detected
P0302 - Cylinder 2 Misfire Detected
P0303 - Cylinder 3 Misfire Detected
P0304 - Cylinder 4 Misfire Detected
P0441 - EVAP Emission Control System Purge Flow Fault
P1136 - Manufacturer Control Fuel Air Flow Metering
P0411 - Secondary Air Injection System Incorrect Flow
P0118 - Engine Coolant Metering Temp Circuit High Imput
P1128 - Manufacturer Control Fuel Air

I replaced all 4 coil packs and I am still having trouble with it. It is idling really weird and also the brake is having troubles too. I am not sure if this has to do with the problems but the remote unlock is working erratically as well. Please help I am going to take it to a shop tomorrow if I cannot fix it myself.

Update

So I cleared the codes and it started to run fine. Still minor problems occurring. Could I possibly need to replace my MAF sensor? If so, where is this located?
