Ok fellas, Here's what's what: (Problem #1) I was sent a replacement control pressure regulator (Dave you asked about this). I installed it. As soon as it was in, I started having other problems right away. (Problem #2) It turns out the frequency valve, even though it was buzzing was totally messed up. It was hanging on by 1 or 2 copper strands. As soon as I brushed the connection with my hand, it completely fell off! (John H. if you have a new plug I can splice on please let me know) With a dremel and a couple of spade connectors I've rigged up something ugly, but secure and functional. (Problem #3) I also put the dwell meter on the diagnostic plug. I observed the proper warm-up indications of a steady meter at around 30 degrees indicating the default setting for the freq valve. Once the 02 sensor reached temperature, it began to fluctuate between 38 and 40 on the 6 cylinder scale. The meter did not show the fluctuation as smoothly as I feel it should be but it was usable so I went lean on th e CO screw to bring it down to 32-36ish (I forget the number in the book, I don't have it with me now). The car seemed happier, more powerful. Then as the engine got hotter, approaching cooling fan kick-off temp, the 02 sensor seemed to totally quit. The freq valve defaulted to a value of around 26 and froze there. The valve is still operating. I could hear it. I know this: The lower the dwell reading the richer you are. The valve slows down and allows less fuel back to the tank. Why would it do this? The 02 sensor is brand-new (like everything else). I put it in 7-9 months ago. It was installed when I had my cat glowing cherry red a few times. Could it be damaged? I replaced the old one "just because". It may still be good and I may still have it around here somewhere. (Problem #4) I did confirm that my idle tube O-ring is leaking with some brake cleaner. I'll replace it tomorrow. I will say this: On the test drives I took tonight, I had the best power I've ever had. I think I'm still missing a little, and I know the O ring isn't helping but I could drive in traffic with confidence now. The question is, what is my fuel economy? Am I still guzzling gas or what?
