I think the issue might be related to the Fuel Pressure regulator, and the hoses involved with that.

The elbow that is connected to the accordion hose (off the air filter) seems suspect, and the rubber coupler between the hard plastic hose and the metal line that goes TO the FPR, is shot (I replaced it months ago, but I suspect that my repair wasn't as air tight as I thought).

The elbow at t-pipe was replaced with the PCV 2 years ago, so I dont that elbow is suspect.

I will hopefully get this squared away tomorrow, and will update (as long as I don't try to blow up the car out of frustration...only joking. Somewhat)
