Ducato Accellerating issue on my 2001 2,8 jtd mobile home

[Dag Aanes]

When engaging trottle slowly in 3:rd or 4:th the engine seams to get less full for a moment and then starting to shake/vibrating. As I increase the rpm the shaking stop. Anybody have an idea what could be the issue?

What RPM are you shifting at? Cleaned out the fuel filter lately?

I am currently chasing an unknown vibration myself. My Motor home is also 2001 2.8 but idTD. I have had a half dozen mechanics look at everything and they all have no explaination. I will watch this thread closely.
