Did your MPG come back as well? Originally I was getting around 16-18 (crap to begin with, but I guess this is normal according to other MDXers) since this power loss issue, I get 12-14mpg.
Did you perform a valve adjustment at any point that may have resolved the issue once the ECU completed a learn cycle?
