200SDi with new injectors - Idle vibration
I've got a 1999 200SDi and I've recently bought (from Dark Ice Designs) and fitted a new set of injectors.
The original ones had more than 150k miles, were knocking too much and the nozzles in the need of replacement (some fuel around the injectors) so I decided to get a set of 4 new injectors.
The problem is that after fitting them, using new washers and new silicone return fuel pipes the engine is on a rough idle. It vibrates too much than with the original injectors.
It runs fine on the road and I have no excess smoke. I've got a Synergy VP and the problem remains with it on or with it off.
I've released the top of each injector to remove any possible air that was on the system. When doing that on injector 2 and 3, it seemed that the idle returned to normal for a bit. After tighten it back, the vibration returned.
I thought that it could be a issue with injector 2 or injector 3 and I decided to bled all the fuel lines again... this time I've noticed no changes on the engine's vibration on all 4 injectors except for the slight juddering when releasing and retightening the top.
I'll try to make a video although I think on camera the vibration is never the same as live.
Can anyone please give me some tips? What can be wrong here?
