1995 Dodge Avenger 95 Dodge Avenger starting and idleing is

My avenger with a 2.0 4cyl. Has had some problems starting and then idleing. This occurs when the car is ether cold and or warm. Upon the first crank the car fires and revs to 1300 rpm, runs for 3-5 sec. Then sounds as if it floods out. Re-cranking, the engine will spit and sputter for several cranks (2-3) then finally start and spit and sputter as if flooding out. There is no tell tale of unburned fuel out of the exhaust. It will idle good for 5 minutes then idle rough. If it is reved up then run fine. It does have some hesitation at low rpm while driving, typically around 1000-1700 rpm. Could this be the fuel pressure regulator or possible a fuel injector issue? I have recently replace the throttle position sensor. The car has a recent tune up new plugs wires and oil change. Although not the fuel filter, also no leaks for any kind.
