Here's a breakdown of the error codes you provided and their possible meanings:

P0100 - Mass or Volume Air Flow Circuit Malfunction:

P0110 - Intake Air Temperature Circuit Malfunction:

P1120 - Throttle Position Sensor Circuit:

P1121 - Throttle Position Sensor Range/Performance Problem:

P1125 - Throttle Control Motor Circuit:

P1126 - Magnetic Clutch Circuit Malfunction:

P1300 - Igniter Circuit Malfunction (Bank 1):

So I would clear all codes and then just turn the key on without starting the engine to see which hard codes come back this is where we should start. Please let me know.
