I'm having a related issue. Not surging as such, but an intermittent flat spot, mostly with engine cold, around 3000rpm. Feels as though it's starved of diesel or missing, but put the foot down and she goes fine and problem disappears. Fuel lines were replaced along with new injectors 2 months ago. Have bought an SCV but not fitted yet, thinking that this problem is not the 'surging' that is normally associated with SCV wear.
Sounds like MAP and MAF clean are the go? When the problem occurs, fuel rail pressure is perfectly stable. Boost pressure also stable. So maybe MAF rather than MAP?
What's the best stuff and procedure to use to clean the MAF? If there a MAF cleaner? Or does one use carby cleaner?
Cheers, StarJunk
