Re: 2000 6.0L runs rough and stumbles

I know you replaced the fuel pump and regulator, but how is your fuel pressure. You might need to find someone (a shop maybe, doesn't have to be the dealer) who has the ability to do some live sensor data logging/scanning to check the operation while running. This may help pinpoint the source of the poor operation. When did you problems start, before or after all of the parts? Did you use AC plugs?
