Well I checked the vacuum leaks, it looks like there fine and it was running good for a couple day, but today it kinda did the same thing but it sounded like it stalled but then when I hit the gas it came back on and then hesitated till I pull over

Thats OK, I may see a common thread with the codes, often one problem will trigger a few codes.
