At least I think I found it. There is a massive air leak at the #2 manifold runner. It can't be seen but I discovered it with a plastic tube to my ear. When I get down under that runner with the tube there is a loud whistle/hissing noise not really audible otherwise. This explains why #2 does not fire at idle, engine fault code 232 and most likely explains a wonky load signal to the tranny.
Walt, you suggested checking vacume, had only 13.5", that quickly led me to the leak. Thank you
Will be installing a new gasket in a day or two.
Will post results.
