I recently had my motor replace by my local VW dealer.  On occasion it will
not start unless I press the gas pedal.  When I hold the pedal down to keep
the rpms up the exhaust smell quite rich and sounds like its flooded when I
gas it (bogging).  If I release the gas it immediately dies.  As soon as its
warmed up it will then idle fine.  Most of the time I can start the vehicle
and all is fine without having to press the accelerator.  It is under
warranty but I know if I bring it in it will work fine and they won't do
anything.
So all suggestions would be appreciated.

Thanks,
Willie
