When engine is cold everything is fine, however when engine has warmed up it starts to misfire at under approx 2000 revs.
I have found that you have to do 30 mph in 3rd gear, 40mph in 4th gear and so on before the misfire goes and it runs normally.
The turbo works OK when there are no misfires.
I have checked the forums on the Internet and cannot find the answer, hoping you can help.
