Occasional loss of Power and smoke at heavy throttle


147 1.9 JTDm 150, '06

Im gona get booked in to my Alfa specialist but wondered if anyone had any thoughts. I have lost power a couple of times when pressing it hard. Seemed to loose power around 3500-4000 revs in 2nd/3rd. Didn't get any lights and it was fine straight after. This has only happened a couple of times in the last few weeks

More importantly and more annoyingly I get a trail if greyish smoke when pushing it hard much more noticeably in 4th 5th and 6th. Also seems like its not quiet as responsive as it should be in those gears.

Ive run two lots of diesel cleaner though it (FORTE) Didn't seem to make a massive difference tho.

Any suggestions that I can pass to my mechanic.

Yep, clean the EGR and check the boost hoses for splits/loose joints.
