OK here are my discoveries for today...
I ran the Enchanced Tests with my OBD-2.com scanner and got the following errors:
P1703 Brake Swtich Out Of Self Test Range
P1780 Transmission Control Switch (O/D Cancel) Circuit Out Of Self Test Range
P1550 Power Steering Pressure Sensor Out Of Self Test Range
The first two, I could see as bogus, but the last one concerns me. If the Power Steering Sensor was bad, would it cause my horrible idle? I would think that it would only cause my car to die if I tried turning the steering wheel when stopped.
For the other readings during Hot Idle, the only ones that were out of range were the IAC and Spark Advance values. The IAC was 37.5% (when it should only be 33%) and the Spark Advance was 27 degrees (when it should only be 15 to 25 degrees).
BTW I still haven't had a chance to hook up my vacuum guage.
