The first code may cause the second code. I would change out the throttle bore and then clear the codes which should fix the problem. Also, check the wiring connector at the throttle body to see if it is good shape.

P0122 - Throttle Position Sensor/Switch A Circuit Low Input:

P0300 - Random/Multiple Cylinder Misfire Detected:

Please let us know what happens.
