Rough idle

[Harry]

Just had my expedition die out on me
It's a 4.6 triton. It had a rough idle when I started it. But then once I got to my destination it stalled. I'm getting a crank but no start. I spent all day replacing the fuel pump and replacing parts for codes p0430 and p1450. No luck.

So I looked up the listed DTC's. P0430 bank 2 catalyst, and P1450 fuel tank vacuum. It would help to know what year your Expedition is and what parts you replaced attempting to resolve the identified DTC's. Unfortunately a rough idle and stall can be from many factors.
