I would check the fuel pressure regulator. It is round, about a quater size and has a vaccum line going to it. If the regulator is leaking gas than it can cause this problem. Pull off the vaccum line that goes to the regulator. Be absolutly sure there is no gas in the vaccum line. If there is, the diaphram has ruptered and there is gas entering the engine that is not accounted for and the regulator will need to be replaced!

Thank you. The dealership has had the car for about 2 weeks now refusing to release it until the problem is found. I am taking my input from Justanswer and giving it to them for reference.
