has anyone had a problem with the nissan 3ltr common rail 2008 model ute .mine after 40,000 kms seems to miss will trying to hold it at 60 to 80 kph new fuel filter service done etc but it is getting bad ?????
when you say 60-80 i assume you mean while you are driving and holding the accslerator in one postion and then it has like a little miss/stumbel ? is it always in the same area eg revs/gear postion if yes. I would suggest replacing the accslerator pedal.
if the problem moves as in it happens all over the shop i would then have a look at the park neuatral postion switch .
or if you feel its a air in fuel issue do a bubbel test to see if air is geting in but if it was sucking air it would struggel to start?
sorry about the spelling hope this helps
