Re: flooding out bad
There is only one way for gas to get into your oil pan and that is past the piston rings, if they are worn bad it also effects vaccuum pressure and throws off fuel regulator and all sorts of other ****.
Do a compression test to find out,

Suspect (potentially) either a stuck injector, or a failed/failing fuel pressure regulator. One sign of a failed fuel pressure regulator can be gas in the oil. (I suffered that side effect, along with bogging, and black smoke rich running, worsening as warmed up, turned out to be fuel pressure regulator). If the injector is loose in the throttle body, or has bad o-rings, can also cause some wonky behavior. Good luck.
Did you put a replacement injector assembly in under the upper intake, this is a major problem with this model. How's your fuel mileage? If this is your prob you need to change it because the leaking fuel goes down in your oil pan, thins the oil and blows your engine. Check your oil, is it over full or smell like gas?
could be clogged fuel injectors or fuel filter could be plugged or your fuel pump is weak and needing replaced,what makes fuel pumps go bad in most vehichles is driving with less than a 1/4 tank of gas,it gets the fuel pump hot and works it too hard
you mat want to check the throttle body and make sure the throttle plate is clean from tarnish build up. you may also want to check for vacuum leaks around the throttl area that can cause an unsteady idle. a faulty MAP sensor can also create an idling problem but run good at highway speeds.
Sounds like you have an injector leaking. Have someone just cycle the key on and off to run the fuel pump but don't crank the engine. If you see fuel dripping from the injectors, unbolt the injector cover on the throttle body, remove the injectors and replace the orings around the injectors.
Float is stuck in carburetor needle and seat probably stuck open remove the top of carbCheck for dirt in the float bowl spray clean with carb cleaner try turning over the motor and see if fuel stops when bowl is 2/3 rds full if not clean again and make sure you have a in-line fuel filter installed also.
Take throttle body off, clean Throttle Body with Carburator cleaner. I had same problem and its the ethynol in fuel that creates a build up in the throttle body which creates this problem. I did what a friend of mine said to do (service manager at Dodge Dealership) it hasnt happened again.
