I do both. I first remove the air cover and then douse each throat with fogging fluid. I use about a 1/3 of the can, the whole time trying to stall the engine. Darn EFI just keeps running, so I have a friend shut it down via the key switch. Then I remove the sparkplugs and spray a whole bunch into the cylinders.

I pull the safety lanyard (no spark) and turn it over a couple times to distribute the fogging oil.
