Default Check Engine Codes P2101 and P1516

Hello,

Need help!! I keep receiving the below two check engine codes on my 2006 Cobalt LT and the reading "eng pwr reduced".

P1516 - throttle actuator control module / throttle actuator position performance
P2101 - throttle actuator control circuit range / performance

The car shakes when first started and will not accelerate properly.

Can anyone tell me if you had these codes and what you did to repair?

Thanks

What were the previous symptoms?

Did you do anything to the car before this happened?
any mods? Or cleaning the intake ?
or unplugging sensors/battery etc?
