those are all electronic throttle issues. here's the basic definitions.
P2106 Throttle actuator control system - Forced Limited Power
P161B Manufacturer Control Auxiliary Inputs Auxiliary Outputs
P1295 Manufacturer Control Fuel Air Metering

It sounds like the engine may have a had failure like a rod knock which would generate these codes.

Can you take a video of the noise so I can tell for sure? Upload it here to the site.

The knock sensor picks up the noise and then the computer thinks its control issue and lights the codes off.
