Codes P0172 and P0175, fuel problem?

When I turn it on it struggles a little and then idles rough but will stay on but then if I press accelerator down let it go it wants to shut off. My fuel trim is showing -34 all my injector pulse are active and normal the
DTC code I got was p0172 and p0175 I was think vacuum so I changed all intake gaskets and check vacuum I have pics of what those show I reset codes and they haven't come back but it is still dying after I hit accelerator also I am not having any misfires.
