Thanks, Yes good ideas, makes sense that it is something loose, and or
something jerking as the engine starts/stops. I initially thought rear
engine mounts. I just can't figure out why it only seems to make the
noise when the engine is hot.  I really  need to listen at the back and
have someone start and stop the engine as it might be more obvious if I
can narrow it down. I could see the air filter or air flow meter making
that noise though.
