Thanks for the quick response. It is the 2.4 DOHC I4 btw. There are two vacuum hoses that need replaced. One I know has to do with the PCV, the other isn't too bad of shape but I'm not 100 percent sure what it is part of yet, but I've never seen vacuum hoses have that kind of effect, high idle yes, but not stalling and sputtering. I will have to look into the MAP sensor as it was one theory that slipped my mind.
I plan on using a better scanner than mine later today to allow me to view the live data. As far as codes, there are none to speak of any more. The light hasn't turned back on and there aren't any stored. That or my code reader isn't picking them up.
The thought of it jumping time was a possibility that came to mind, but again, I would figure that the light would have triggered by now. Also, before the original codes were cleared, the vehicle had a very hard time starting and sometimes wouldn't. Now, it'll usually start, but acts almost as if one or two of the spark plug boots weren't connected.
Unfortunately, with this being my friends car and a few months old issue, it is hard to describe how exactly the problem came to be. She said it started acting this way after a trip to visit a friend.
One of the reasons I'm leaning toward a fuel issue is because the O2 sensor was picking up a lean condition. Something had to have been preventing enough fuel from entering the cylinders or somehow too much air is getting into the engine.
