Default Surging

Hi all, have a surging problem when at roughly 1500-2000 revs. I'll be travelling at 100km p/hr then the revs will drop even though my foot is still on the accelerator. I have a 2012 D22. Any ideas? Cheers in advance!

There's some info here.

Or just Google YD25 engine hunting.

Good luck!

That will be the scv. If you can put a scan tool on it and monitor rail pressure. It should be steady at 30 mpa at idle. pm me for link to our web page with more information.
