The return to normal did not last long, and my car is now sputtering again with MIL back on and showing the same codes of lean/rich and multiple cylinder misfires. No MAF codes, though I was wondering if that could be the problem upon reseating of the airbox. Here are some codes with a few pulls in second gear:
group2 time group 2 time engine

10.11 51.31 16.36 50.94 3720

7.69 59.11 17.69 58.74 4400
16.22 59.64 24.03 59.25 4360
I have much more in the log; group 32 adaptation % stayed unchanged at 6% and 0.8%.
Failing MAF? Any other thoughts?
This is with 91 octane tune on APR chip.
Many thanks in advance.
