Hi all I have a 1.9 DCI trafic van
I just replaced all the engine mounts and now the van shakes like a cocktail shaker its idling at 650 RPM

When I hold the throttle to 900 rpm its as smooth as a baby's proverbial


I had a guy come out and put a flash tune in it which made a slight difference but he wasn't able to adjust the idle speed
I have been searching for a while now thought there might be someone with a similar problem that knows the answer I know its a van but its the same 1.9 engine as the megane great engine great van just needs the idle lifting
