it will be a vacuum leak at the injectors or it may need a gm update, cause if you are burning the new gas with the 10% added to it of that ethanol it will do this just had problem with our v 6 torrents or go to mid grade, but only two things gm could figure, or use hp tuners and adjust ecm yourself.

code 300 and 171. both 02 senors are new, no vacum leaks, replaced spark plugs and coil pack. ill change out the fuel filter when i get some money, not that hard to do. i have yet to check the injectors.
