My new hoses into and out of the idle control valve arrived tonight, so I'll throw those on and do some more diagnostic work tomorrow. The symptoms seem like it's the OVP relay, I just want to make sure before buying another one. I rigged up my ammeter to measure the idle control valve or EHA valve while driving around, so I'll try it out tomorrow (so I don't wake the rug rats who are already in bed). With ignition on, I'm definately not getting almost no current at the idle control valve (.14 ma), which seems to point to a OVP relay; but I'll verify that and also check the EHA tomorrow.
