The codes P201 - P208 are not valid codes. Codes must be 5 digit with the first digit being a letter as the other codes you listed were. It sounds as if you have more than one concern present. The concern you've had for like 6 months now with the P061B and P2106 is most likely related to the throttle body/TP sensor assy. Buy a new throttle body assy, not a used one, and replace it. Clear the computer memory and go from there. Drive it awhile and see if any of the other codes return. The P151a is related to a intake manifold runner control actuator concern, and the P0446 as you already know is related to the evaporative emissions system. I wouldn't worry about those unless they return.
