Are you still free of the P0171 and P0174 codes?
I have had these for a while. The GXP is going in for its 75K service soon and I think I might have the FPR checked while it is there.

Codes are gone. I can't say all that I did wasn't a help in resolving the codes but I am leaning toward the FPR.
Have them check the intake coupling (boot between TB and intake manifold) because this is a common issue with the N* as well.

The GXP got it's 75K service on 03/28.
Here is the summary.
They found a leaky intake "gasket", fouled plugs and a dirty throttle body.
Service performed: Replaced intake "gasket", installed 8 new spark plugs, performed throttle body service and cleaned the fuel injectors.
The "gasket" was the short boot between the throttle body and the intake. There is a nice new shiny one there with a few traces of some lubricant they used to ease the installation.
The extended warranty paid for the "gasket" replacement which was about half the bill. The plugs, injector and TB cleaning part of the bill was mine.
The P0171 and P0174 are gone. The car runs much better now so it was definitely worth the trip to the dealer.
