I have a code P2135 which came up with a reduction of power on acceleration as if the vehicle was in overdrive from a standing start. What can be done about that?

You will have to fix the cause of the code its a safety feature if the throttle by wire system as a failure it goes into reduced performance mode. Do you have a scan tool that can read live throttle position sensor throttle pedal sensor data etc?
