Mike, thanks for the info. I've already replaced the hoses and cleaned it. I get proper operation of the ICV when connected to battery. However, the connector to the ICV is only providing 2.5v KOEO. The manual states 12v. Also, when I disconnect the connector there is no change in engine speed. Other threads have pointed to the OVP but the wiring diagram for this model year shows the ICV wired to the CIS-E control unit, not the OVP. So, maybe there is a still a connection but it's not clear. At any rate it's a nuissance. Other than that the car runs like a champ.
