Random Misfire, Rough Idle, and CEL

Random Misfire, Rough Idle, and CEL
Hello.
I own a 2009 Audi A4 with around 150,000 miles on it. Over the last few weeks I have experienced: A rough idle, a hesitation while accelerating, random misfires and a permanent check engine light. I have fixed & replaced the: Coils, Spark Plugs, Air Filter, and PCV Valve. I will note the error code from the scan always points to the PCV Valve, but I just replaced it with a new one from Audi.
What else could it be? I have read that it is possible it could be a timing belt or maybe the MAF (Mass Air Flow Sensor).
Any help would be appreciated. Thanks
