Hmmm... sounds similar to a problem I experienced with my Lotus:
Hesitation and "one-dead-cylinder" feeling until throttle-back, after a
stop to check this-or-that component, the problem would go away for
awhile.
The important point was that it happened to go away after stopping to
fiddle around. It sound like an inadequate fuel flow problem of some
sort -- mine turned out to be crap jammed in the intake filter of the
electric fuel pump. You may want to check the following (depending on
how your MG is equipped - bear in mind I know nothing about your marque
of automobile):
o Inline fuel filter
o "Rock strainer" carburettor bowl inlet fuel filter
o Intake filter on electric fuel pump, or diaphragm on
mechanical fuel pump.
o Fuel tank pick-up filter
o Fuel lines for kinking or partial blockage
o Accelerator pump
o Float valves
Hope the easiest thing to check turns out to be the problem!
