Hello,

It sounds like the engine is in limp mode because of a computer issue. Lets start by running the codes to see what come up so we can go from there to fix the car. Here is a guide that will help you:

The code P2128 is telling us you have a problem with the throttle actuator. I would try cleaning it first. Here is a guide. Disconnect the battery before you begin and clear the codes once completed.

Please let us know what happens.
