Throttle issue

When you take foot off brake car does not move. Surging upon accelerating. Lacking or delay in throttle response. Car was just in beach Ford having the electronic throttle body replaced about a month ago. In an effort to repair car also had a fuel pump replaced. No codes or wrench light. Gets worse the more you drive the car and the hotter the car gets.
