hi guys it's Ivan, I have a Nissan primera 2.2 dci primera, had egr valve stripped and cleaned replaced turbo boost solenoid valve, ran ok for 4 months but now getting a power dip when accelerating it will red line in second but third and fourth gear power dips at 4 thousand revs take your foot off and accelerate again and it will red line again not that I drive it like this. Any ideas would be welcome I was thinking maybe maf sensor ? But tickover is not fluctuating it's nice and steady at 600 rpm any ideas would be appreciated.
