Welcome to Just Answer, Wow it looks like you have covered about every angle and spent a lot of time and money.

One thing that allways trips people up om faults like this is often overlooked and is very common and is water in the fuel tank, this can then foul the plugs or injectors, try removing the fuel filter (after depressurising) and drain it from the rear/inlet into a glass jar you can then see the water settle at the bottom.

Another possibility is a sticking EGR valve as these can cause all sorts of trouble.

I hope this helps, best regards, Vauxdoc.
