Ok, I took off the intercooler and found the coupler, it slid right off without even loosening the clamp...thanks Subaru...
Anyway, I took the coupler off, then applied the clamp directly to the intercooler to throttle body tube and put everything back together.
I reset the ECU and the A/F Learning numbers are all within spec now. Table C is now in the 2's like the other numbers are during idle. I'm going to give it a day or two and let it learn a bit, then post up another log.
This SEEMS to have solved my problem.
