James,
You need a "MotorVac" machine to do this type of cleaning. I haven't heard of individuals figuring out a way to get the same effect of a Motorvac without the machine itself.
Try this link for more info: http://www.motorvac.com/mcs245_pg.html
I can't imagine it's exclusive to the United States.
I have also used FI cleaners in the bottle with mixed results but after a MotorVac my car was running like new. Prior to the cleaning, the car could barely stay running, was stumbling, and all that bad stuff.
But as my mechanic said going in, it's really a crap shoot with hesitation since so many things can cause it.

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?
Thanks,
James

James,
In my experience, hesitation has been caused by either faulty spark plugs,
an old fuel filter, or most frequently, clogged injectors.
I've cured it by doing a motorvac fuel injector cleaning. Not sure if you
have motorvacs in the UK, but basically it's a system that bypasses the fuel
line and run the car on FI cleaner for 20-30 minutes. This "super shot" of
FI cleaner does the trick for me.
HTH,
