Like I said in my original post I could not get a good peddle till I activated ABS and bled them again. I was lucky to have a nearby dirt road to use

Thanks! No dirt road close by, but I did use ISTA to activate the pump for each tire and that seemed to help some. I'm about to try round two to see if it fully resolves the problem. I guess the amount of mushiness made me wonder if it was a totally different problem.

Side note, LTFT for bank 2 went down to -0.78 and held steady. Bank 1 still -3.xx except in certain RPM ranges, so have to track that (air leak) down. Gas mileage went back to 'normal' - it had dropped to 12.6 but now back to 15.x+ stop and go.

Edit: Round 2 found revealed some air in the line for the driver/rear tire. Much firmer now.
