Pay attention to the plastic adjustment connector (grey part on the cable, just below your yellow circle above). Hard to tell exactly, but it looks like one of the latching fingers may be broken. This is a very common failure, but that connection will now be loose, and can cause binding (including possible stuck throttle). There are several threads on this. Easy fix is to surround/secure the connection in the bracket with a small cable-tie (or two).
