Code P2101- Throttle Actuator Control motor circuit

Last Sunday I was driving home 2 hours away and the car started acting funny about half way through. I would give it gas and the rpm would jolt up and down causing back fire. When I was about 25 mins away I lost all boost so I puled over and noticed it was a coupler that had blown off. I limped it the rest of the way. By the time I got home there was a check engine light. Which was the P2101, I shrugged it off think it was due to the coupler. It didn't go away so Tuesday I cleaned the throttle body and it went away later that day. Thursday I start the car and the check engine light is on and I'm driving it to work when it goes into limp mode. I limped it back home. I replaced the throttle body today, I thought it was the throttle body gone bad. Nope, still in limp mode. I did the 10 second on then 10 second off to reteach it.

Any ideas on what it could be? The code popping up is still the P2101
