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.

But what would cause those to set off? My gas gauge has been acting funny it shows how much gas I have then the numbers go up then down. Would that be something that could cause it? Could it be my fule pump? Or sending unit?

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