Leaky injectors are Common problem to flooding.Best to have them removed/cleaned replaced.And Plugs don't have anything to do with the car FLOODING(Mechanically wise).Plugs are electrical.Flooding is Fuel.

Does this mean the rest of the day when the engine is already warmed up, it starts each time??????
By being flooded in the morning, does this mean it's just reallllll hard to start but finally starts up???????????????
A waterthermo sensor with a broken wire will give the above symptoms. Its input to the ECU is on the GREEN/WHITE wire in the middle plug of the ECU. If you backprobe it in the morining it should read above 1vdc and if its a pretty cool morning it'll be above 2vdc. Fully warmed up it'll read about a half volt.
A lack of this signal makes the ECU default to a temp of 176 F which means the amount of fuel injected will be SMALL vs if the waterthermo input was good on a cold morning, whereupon it'll inject LARGE amounts of fuel (making it start better with a cold engine).

Y-pipe? Probably not.
Spark plugs and wires, yes. Your injectors may be leaking a little and it's not sparking properly during cranking causing it to flood. Replace them both and see what happens.

Get a compression test done first thing before you do anything else.

I had a bad cold start flooding problem. Saw a suggestion from HAILERS in another thread to replace the water thermosensor. It worked. $15 and 30 minutes. Thanks HAILERS.
