you must need a tune up, plugs, wires, cap, rotor, and fuel filter at least. you need to determine why your engine was flooded. are you sure your engine was flooded?? who diagnosed this? when you started the car, was there initially black smoke, or a strong smell of unburnt fuel? i wouldn't be surprised if this comes back, if it was caused by your engine flooding for sure, check the tps, thats really the only way a efi engine will flood unless you crank the car for a while with a weak ingnition system. it could have been flooded but it would take an excess amount of cranking and a very weak ignition system. that would be your fault if thats the case but if you had to crank it for a while, you have other issues. do a full tune up, i bet your whole car feels different.
