My Ducato 2,8 jtd -03 misfire when reach about 2100-2300 rpm.
Have changed ECU and pot.meter for speed, but no help.
My local dealer in norway can not understand it....

When it reach about 2100-2300 rpm, its misfire. When i go higher or lower than 2100-2300 rpm, or give more speed, its ok.

Anyone knowing ?

Check the accelerator pedal. It is a fly-by-wire operation and can have a fault at a certain position. It has happened on a few Ducatos.
 
Just read your post again, if you can consistently get it to misfire then it should be very easy to find by graphing the sensor outputs, if its a small transient error a digital oscilloscope might be required to catch it.
