Hello,

Those codes could refer to extra unmetered air detected by the O2 sensor. Could it be when replacing the AMM you accidentally tightened any air leak past AMM? You could put back the old AMM, clear the codes and test again. Also look for any cracks at the old AMM hose attachment. Rarely happens but possible due to past over tightening (the crack enlarge under stress).

Hope this helps,
Amarin.
