I checked this white plastic line and one end did not seem to be secure. After snugging it up and clearing codes, number 4 and 5 did not reappear. I drove the car for about 75 miles and got the check engine light again.
This time it is only code 19.

What is the procedure for resetting the computer adaptation algorithm and is that most likely my issue now?

Thanks for the help!

John
