Chattering APC & Base Boost, Part II

In our last episode, I complained about getting base boost only with a chattering solenoid on decel. Sound does not disappear when brakes are applied.
So I checked the APC solenoid as per Townsend. Solenoid gets batt voltage, ground is good, and no shorts. Resistance from terminal to terminal is about 32 ohms. Blow-through test on port "C" with solenoid unplugged gives air through port "W" but not port "R."
According to Townsend, Blow-through test with solenoid energized should give air between "C" and "R." However, I also get air out of "W," and Townsend does not mention this result. Bentley is unclear.
Should all ports on the solenoid be open with solenoid energized?
BTW, I took the unit out and sprayed WD-40 into it. Then I blew out excess by energizing the solenoid.
Time for a test drive.
