The o2 reading at .9v shows that it sees it is rich, very rich..... it should fluctuate from .4-.5v if all is operating properly.

^^ This. And it goes right along with what you are saying that it is getting lower fuel mileage than expected. A 561 ECU is not a reliable ECU. The 933 is a far better ECU.
Please tell me what is different about a 2.2 sensor vs 2.4 o2 sensor.
