If you change the throttle body, you may have changed the wrong part as the pedal sensor may be the issue. Thats why you get a diag before throwing parts at it.
Once we have the code, we can assist you further

My caprice royale 2005 has the same problem. Safety Mode - Reduced Performance. My mechanic told me that it has throttle body problem. But before changing the throttle body I have changed the battery and error has gone and my car is running gud. : P
