Please clear all codes and with the scanner still connected turn the key to the on position without cranking the engine over to see what comes up. Does the engine run?
Cheers, Ken

The day after I posted I found the o-rings went bad on fuel injectors. Waiting for them to come in today to continue. Thinking there was a small leak I did not see, but not sure if it would set these codes.

By these numbers is looks like the MAF is having an issue which can be caused by a MAF sensor problem or a partially clogged catalytic converter. Here are two guides to help us see what the problem is:
Not really that would be a separate issue. Do you think that is what is slowing the car down? Can you make a quick video of the problem and upload it in your response so I can what is going on?

Sorry, I just saw this. I am more concerned with the check engine light. I got a new MAF and installed in no light, but I am getting this now:

How does the engine seem to run? If okay I would say the computer is having an issue. Please remove the PCM and look for water damage. If you clear the codes and then just turn the key on without starting the engine do any codes come up?

This code is for the thermostat sticking open which can cause some issues. Can you please remove it to see if it is stuck open?

These codes are oxygen sensor related can you make the sensors are plugged in? Also, if you have the wiring connectors off of them or any other sensor please check then to make sure they are plugged into the right place. BMW does not have unique electrical connectors of each sensor. It could be fuel related like bad gas. How did it run before you did the repair?

About the same. I feel it is running worse because of this extreme heat.
