sounds to me like the engines running too rich maybe, that would explain the
bogging and stumbling, as to where to go from there, check plugs for colour,
find the cylinder or cylinders that are wrong, and try to adjust the mixture
on them cylinders, i had a problem where the car was fine when cold, when it
warmed it was impossible to keep the revs up, turned out an injector was out
and the 6th kept it running, then after i replaced the injector it ran very
rich and behaved like your description.
