Without an oscilloscope you'll never see if the actuator or oil control valve is failing. Take out the solenoid & clean it while applying power & ground. See if that helps.

There is also a filter for the OCV located directly below it on the block. It is a wire mesh filter, which can be removed and cleaned.
