Mine is also 99 SC400 (92k miles) and just noticed solenoid leaking black butyl sealant on the a/c compressor. Engine rpms drop very low once warmed up and only in Drive gear (stalls when trying to turn). Did you have the same with your car? Can this solenoid be fixed? (replacing capacitors or something...)
