They checked it, said the motor was bad, rebuilt it, including new cable/harness and sent it back. Installed today and it runs worse than ever.

Can't do much over 30. If I put my foot into it, it goes into limp home. Barely made it home. 25 MPH on freeway, stalled crossing busy intersection.

So....

Does it need to be reset after installing the ETA? Could the throttle module be bad?
