Does it sound right that the throttle body and throttle pedal sensor need replacedtofixanissuewithlossofpower

What is your question?

Vtm4 light comes on along with vsa activation indicator. Followed by vsa light. Engine will continue to run, but when you slow down, I have no power, only idle. Turning key switch off and restarting clears problem. Sometimes it comes back immediately, sometimes it will not for a long time. Mechanic says codes shown are P2138, 91-1, and 77-1. P2138 is App sensor a-b correlation and this is why he says throttle body is issue.

What makes this problem better or worse?

Possibly warmer temps but not 100 percent sure
