Flooding

what are some causes of engine flooding. I have a 2005 f-150 and the engine is flooding on cylinders 3, 5, and 7 and cylinder 1 comes and goes. Can anyone give me some insight on my situation.

  • Leaking fuel injectors.
  • Bad fuel pressure regulator.
  • Fuel pressure too high.
  • Lack of spark.
    are the first things that come to mind.
