Thanks for the suggestions. The spark plugs and fuel filter were changed at 
the last service interval, but had no effect on this problem. To date, the car 
has had two doses of injector cleaner run through (I usually do so every 
3000-6000 miles, depending on the formulation). However, I'm not familiar with the 
procedure you describe where you bypass the fuel lines, etc. Is it something 
you do yourself, or is it a garage job with specialist gear?
