Here you can see that when VVT is not activated Intake angle 2 is more retarded. It evens out when VVT becomes active. Shortly after, the exhaust VVT becomes active. This causes a slight delay in intake VVT, as to be expected. However, intake angle 1 recovers nicely. Intake angle 2 oscillates quite a bit longer and slowly recovers. Either oil is being impeded to the cam phaser or the cam phaser is sticky.

This really is a nice graph.
