Update to the original post here,
I checked the map sensor and hose which were both clean but the pipe on the engine side was almost completely filled with black crudd so cleaned that.
Also installed the blue spring upgrade kit. Idle has been great ( better than ever actually) and seems that it took the lack of power / chugging out of it too.
Not sure which one fixed it but it was 1 or the other.
Thanks all.

After you install the spring kit, see if you can find a way to do a cylinder contribution test to find out if any of the injectors have been damaged by low fuel pressure.

How do you do a "cylinder contribution test" and will that show an injector that is bad or going bad?
