If you are having the same issues, I first suggest checking fuel pressure to confirm it isn't too high. Here is a link that shows how it's done:
Pic 1 below shows the manufacturer's specs for fuel pressure.
If the pressure seems within spec, the next possibility (if it is flooding) is the engine coolant temp sensor. If the sensor is telling the computer it's extremely cold, the computer will make the fuel mixture extremely rich to allow the engine to run in those conditions.
Here is a link that explains common symptoms related to a faulty coolant temperature sensor:
Interestingly, if the sensor sends a signal, the computer doesn't know it's wrong, so it doesn't set a code.
The best way to check the sensor is by using a live data scan tool. Simply go to live data and confirm the temp signal is where it should be. For example, if the engine is cold, the sensor should indicate near ambient temperature. Check this as well.
I attached a couple of pics below showing the location of the ECT (or in this case WTS). Here is a link that shows how one is replaced:
Let me know if this helps or if you have other questions.
