Are you sure of the code? http://obdii.com/dtcanatomy.html gearchatter.com has the '04 GTO code descriptions, didn't see it there.

it's a drive by wire code, so it may not be in a 2004 list

EFI live has it listed as

accelerator Pedal Position (APP) Sensor 1-2 Correlation

So it sounds like a pedal issue.
