I've heard there is a reprogram for this. Dose anyone know the TSB #?

No tsb that I have heard off. There are newer calibrations out for our car but they don't specifically address the P0171 code.

i talked to a tech at the dealership near me, he said those reflashes are only for cars that are having those problems. you would only know by them hooking the car up to there computer. so there not really update reflashes, there more like patches for certian cars that are having computer issues or problems that can be fixed by a reflash. as far as detials on what each thing does i have no clue lol.

Is there a reflash for the rpm gauge jumping up and down when comming to a stop? that crap is annoying, my fix is to give it gas and it evens out, but I dont think you should have to do that.
