Answer
Hi Antwan,
I don't have to give you very much expertise because you seem to have a pretty good guess as to what is the cause of your problem. I hadn't heard of that situation before but as I look into it you seem to have made a good case. Because you mentionned injectors I assume you have the 3.0L V-6 engine. And it turns out that the pressure regulator on that engine indeed does need vacuum and has a vacuum port, so that if the internal diaphram was to leak then gasoline would be drawn into the intake manifold which probably caused a 'flooding' like effect on the engine operation including fuel in the oil, etc. The regulator is located on the front center upper level of the engine, just behind the MAP sensor and alternator. It is mounted in the return line from the injector ring so you will see a gas line returning to the tank from it.  But you will also see a vacuum line that goes to the intake manifold on it. You could check that hose to see if it too smells of gas. With a good regulator you would not have any such smell in the vacuum line. So I can't think of any other source of excess gas unless one of the injector had broken down, but you believe the injectors all are good.
So go with your surmise and see if you can smell gas in the vacuum line.
