Misfire All Cylnders

EDIT: Two minutes after posting I found this thread https://www.m3post.com/forums/showth...ighlight=90465
I also swapped from OEM NGKs to the new NGK 90465 spark plugs. Guess I am going to swap back to OEM. I'll keep you guys "posted".

Need a little help from the forums. Just replaced Bank 1 throttle actuator because I was getting the following codes

P1628 (pending)
Engine:
2B21 - Throttle valve actuator pre-drive check, bank 1
2B57
Traction/stability control:
5E19 - CAN DME/DDE Torque Reduction Not Possible

I had Bank 2 go out about two years ago, so I am pretty confident this was the problem. This time, I saw that there are aftermarket suppliers who provide repair kits for the gears, however, I bought a new throttle actuator from BimmerWorld.

While I was in there, I had been having a small leak from my valve covers, so I took the opportunity to replace the gaskets.

Upon startup, I started getting the following codes. I've gone and made sure all connections were tight, replaced the Fuel Tank Breather Valve, cleaned the MAS sensor, and checked the grounds were tight.

The next parts I was going to replace in order are Vanos valve, camshaft sensors, and alternator. I have read that bad O2 sensors could cause this as well. But wouldn’t all these items throw their own codes?
