When I just start the car (cold engine), the car seems to be working incorrectly, shaking, as if it were nozzles?
But the car after 4-5 minutes of work goes quite normally, even pulls well, no driving problems.
What can it be?
Maybe diesel injectors? PCV valve?
By the way, it's like I hear a little alternator.
I enclose a video of the operation of the engine.
Any advice how to resolve this problem?
Thanks in advance
