I haven't received alot of help from the furom but I wanted to share what I discovered. The terminal number 85 is the ground for the relay that sits behind the OVP. The terminal 30 is battery current at all times. So, when I jumped the two points, I blew the fuse on the OVP and have been chasing a low idle start ever since. I'm not sure if this is coincidental or I shorted something in the idle control valve but I replaced it. Now, my car starts hot and cold, with fuel enrichment and initial idle increase as expected, gradually settling down to about 700 rpm. With the new meter, I'm getting reliable readings of the eha valve current. It is 19.80 mA at KOEO and about 10 mA while cranking when cold. This amperage quickly and gradually drops as the engine temp increases and the dile continues to fall toward 700 rpm. At 80 degrees C, the eha current is adjusted to fluctuate between -00.40 and 00.60, I prefer it to be slightly rich. I'm still experiencing a pop in the intake and I notice that the current to the eha upon acceleration does not reliably increase, especially if I step quickly on the pedal to quickly raise the rpm. Gradually increasing the idle is less problematic. I'm going to check my fuel pressures again to confirm that they are within the acceptable range. It is a new fuel distributor and new fuel injectors. Hopefully, these are fine. I put on a new fuel sensor and it has about .7 volts at idle and the voltages on pin the top and middle pin are what factory specs require and increase to almost 5 volts as I move the air flap. When I check the resistance on these two pins, the resistance changes but there is a point when it goes to infinity for a second and then the resistance comes back. This is notices especailly with sudden movements of the air flap. Can this be the reason for the occasional pop in the intake when sudden acceleration. Finally, I noticed that the fuel regulator does not hold vaccum on the vacuum connector designed to sliughtly increase fuel pressure when vacuum is high, like sudden steps on the gas. Any help would be appreciated. I'm making progress.
