This nut often falls out and rolls under the intake/throttle area, where is has to be fished out.
To re-install, you can remove parts of the intake, or use some method of hold the nut while
threading the bolt into it - I used tape on a box end wrench to hold it. Did this job many times
over the years with my various wbx starter and trans issues, including twice on the side of the
road, so I got good at it....
