I am guessing it's in the intake. Pump has good pressure and is new so I doubt that is a issue. I don't believe the reg or injectors have either been changed so I think that would be the issue.

Looked washed I would say. A decent about of carbon I could see down there though. imo, mpg was not good. I never drove it far but it was doing worse then it should have.

The next step would be a closer visual inspection of the injectors and fuel pressure regulator. However, if you open the plenum be sure to have new gaskets! If the regulator is leaking it will be very obvious. The passenger side will be really clean looking. It should be dirty looking if its not leaking.
