This morning I took a preliminary look at the car. While cold, the idle hunts from 0-2000 RPM. I checked the codes (2 & 17 - NE Signal and O2 not changing) and then cleared them. All vacuum hoses look fine (oops, didn't check on the back of the intake manifold but I'll check later). I bypassed/jumped the bipes CAS connectors, disconnected the TPS connector, jumped GND/TEN, visually inspected and cleaned the CAS connector at the CAS, and played with the idle screw (yeah, I know). The car is still hunting at cold idle. Will try to take another look at it later today. Any ideas?
