For those who might pull this when doing a search, the problem was an additional vacuum leak that I had missed. The 4th connection, just out of the picture range, had a sliced connector. If you put your ear up to it, the leak was obvious.

Steve at Pinnacle (Woodridge IL) helped me out. He and Brian are great guys and I highly recommend them.

The 190 lesson learned is to check ALL vacuum connections before tearing things up looking for valve or actuator problems.

Thanks to all those who chimed in.
