First of all, this is a fantastic tool for new Porsche guys like myself, so thanks in advance for any advice you can give....
This is probably a bit long winded, so bear with me. I recently bought a 01 996 Turbo. Beautiful car with tasteful mods both inside and out. Previous owner was running straight exhaust off of the turbos and it was just too much drone for me as an occasional nice weather driver. Prior to my decision to replace the exhaust the CEL came on and it was 02 sensor related. Fortunately the seller gave me his Durametric diagnostics kit so I'm able to check codes and reset them at will. Erring on the side of caution I ordered 4 brand new Bosch 02 sensors and installed them with the 996 Tubi exhaust system I also received with the car. I was hoping that would be the end of my issues, but alas after a test drive with the new exhaust/02 sensors installed I am throwing codes once again as follows....

P0045 Boost pressure control valve final stage open circuit

P0130 Porsche fault code 10- 02 sensor ahead of cat cone. bank 1

P0300 Porsche fault code 507 Misfire detection (total)

P0301 Porsche fault code 508 Misfire Cylinder 1

P0302 Porsche fault code 510 Misfire Cylinder 2

P0303 Porsche Fault code 512 Misfire Cylinder 3

Is there a reason why only one bank now is affected by misfires? Was I supposed to disconnect the battery to reset the ECU after installing the new 02 sensors? Forgive the million questions. I'm an air-cooled vw guy and am new to the Porsche thing. Just hoping someone here has had a similar issue and can help me nail down exactly what might be plaguing my newest addition. Thanks in advance for any help or advice!

I've heard a cam solenoid/sensor may also be the culprit here. Curious to hear what the experts think...

 

Be sure the electrical connector to the N75 valve on that bank is secure.
