Having problems when running my T4 155hp.
Runs well through rev range except between 10000 to 12500 when it starts runing very lumpy and smokes alot.
The engine only has 150hrs and recently been serviced Any ideas much app. /forums/images/graemlins/confused.gif

Sorry not to be able to help, but hopefully you have a 0 or two amiss?
I know modern diesels tend to be higher revving but surely not 10k to 12.5k rpm?
