An easier way is a scanner that can actuate the Variocam actuators.
You trigger an actuator at idle with the scan tool and you hear and feel the motor run differently= rougher. You can trigger one side at a time.
Both of my scanners can do it, makes testing the function of actuators, injectors and other modules simple.
If you decide to go for another scanner look at Foxwell. Mine is the 520NT Pro, under $200.00 US.
I think they have upgraded to a 530NT now as mine is a year or two old.

Yes that is exactly the kind of test it needs to be sure
