I'm chasing APC gremlins and I need some help.
I upgraded my '96 intercooled CS with a '97 CSE ECU/APC solenoid/turbo gauge cluster, replaced vacuum hoses, but am getting base boost only with everything connected.
I have tested the APC solenoid, it checks out (Ω & air passage); I cleaned it (it was amazingly clean when I got it) and shot some light Si lube in all 3 ports, gently removed the excess. It clicks when ignition is turned on and very-faintly buzzes in anticipation of the fun.
When I disconnect the "W" hose, I get full boost/overboost (yee haw!) to the point of fuel cutoff.
Testing the APC solenoid harness with ignition on, I get about 5.5V on one side (blue wire) and practically no voltage on the other side; the APC fuse is good.
Lots of internet research has provided no clear answers - I sure could use some help with this one. TIA
