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
