You can drive the car you dont have to let it idle. RX7's have the same problem. Flooding occurse when you shut the car off during the cold start. Not driving it. Its b/c the cars are fuel injected and if you dont burn off the excess fuel thats inside the engine from it being injected and from whats left oer from the previous drive you will have to much in it. Hence the flooding.
Cant you just pull the egi injector fuse and turn the ignition a couple times with the pedal on the floor to unflood it? Then put the fuse back and and start it? Thats how i unflood my 7.
