I bring the rpm up to 3k and hold it there as I turn off the key. Only takes a second. Again, I'm not sure it does anything, but I've not had a problem with a flooded engine yet. Considering that even after 3 months I STILL haven't successfully removed a spark plug, I'd just as soon not have it flood.
While I'm sure that this always works for you, what this is really about is shutting the car off while the engine is decelerating. The ECU cuts fuel in decel so even if you just fire it up when it's cold out (AKA super rich) this should keep you from flooding. Rev to 2.5-3k and then let it fall 1000 rpm before you turn the key. If you have a PFC you can even watch the injector duty as you do this to learn how this behaves.

Damn, its already been a full year since this thread lol
My habit hasnt changed though, although i never had a flooding problem even though i didnt let the car idle long enough before a shutdown.
Im not sure if thats because i have a healthy engine/fuel system etc etc, i just consider myself lucky i guess.

I believe the flooding issue is with the 2nd Gen. There was a defect in the ecu programming from the factory.
If you were to start that car, say to move it from one part of the garage to another, and not let it run long enough to come up to operating temp., that damn thing would flood religiously the next time you went to start it.
The throttle 'blip' and a quick ignition cutoff, supposedly shut down the injectors and as the engine spun down it pumped the excess fuel out the exhaust port.
I think it didn't happen when the motor was shut down hot because the heat from a hot engine vaporized the excess fuel. Thats why the flooding problem only occurred when the previous engine shutdown was when it was cold.
In the old days the throttle 'blip' was to insure that the carburetor's float bowl was as full as possible for the next start to minimize excess cranking
