The engine speed of Kerry elegant van fluctuates up and down when parking. Is it normal?

Whether rapid acceleration and high-speed stable driving are normal during driving. It is normal for the tachometer to fluctuate slightly when the parking gear is loose, so don't worry (it won't affect any use).
