SOLVED!
I replaced the entire ignition systems again, coils, spark plugs, wires. I replaced the IAC and went back to the OE after a good cleaning with cotton swabs and contact cleaner. Replaced two MAF sensors, before replacing the entire thing. Bingo! We have a steady, altho some what fluctuating idle, and no spark knock. I'm still down on power but I believe that's is still to do with a partially plugged catalytic converter. I will be doing a full exhaust sometime this year. I've since bought a GMC C5500 and that is getting my attention now.
