this sounds like a gas pressure regulatur. a few minutes after starting,you start smelling fumes,and are getting bad gas mileage right?

I also have a 2004 XC90 and a couple of months ago I had the exact same probelm... after multiple visits to my dealer's auto shop they figured out that it was the fuel pump. They replaced the fule pump and the smell disappeared. Good luck!

Your problem is typical for these cars. The throttle position sensor is bad. Go to Auto Zone and have them check the codes to confirm this. i've seen this many times, that's usually the problem. It makes the car feel like the brakes are on. Hope this helps. Let me know. Phil

the fuel injectors may be laeking. on the 2.4, start the engine ,look at the rear of valve cover to see if gas is coming out of the injectors at the electrical connector.

The OBD II code for P0400 is Exhaust Gas Recirculation Flow Malfunction.
I'm sure the only thing you have left is you may have to replace the EGR valve or check for any leak from the vaccum lines going to to EGR valve.
