You may want to see what OBD code(s) are in the system. Put a good bi-directional scanner on it and when it goes into limp mode write down the code(s) and take a look at the freeze frame data if you can.

Let's back up. What made you replace the throttle body? What brand part did you use?

When you say its "going into limp mode", what do you actually mean? Check engine light flashing? Or is it on steadily? Does the instrument cluster readout say "reduced engine power mode"?
