Perhaps some form of vacuum leak.
Or MAF sensor but there are ways to test it.

Yes, I agree. As you pointed out though, the downstream O2 sensors do look like something is up, so I won't ignore them.
The MAF appears to be operating properly, 15 kg/hr at idle and the Voltages looked about right last time I pulled data. I pulled some data on my test drive after changing the fuel injectors but I was in a rush and I'll need to pull more. Will pull MAF, O2, Fuel Trim and Engine Load data next test drive after I test cats, smoke the intake and replace the spark plug tubes.
Thanks again!
