AMM life ? :>( (longish)

Does anyone know what the average MTBF (Mean Time Before Failure) of an AMM is? Car runs fine, boost near red, replaced O2 sensor, fuel filter, air filter, cap, plugs (Bosch Platinums),no overheating (and its been hot), all vacuum lines holding but CEL comes on once engine has warmed, no change in performance. If I keep driving (not hard) eventually CEL goes out. If I stop car for the day and the CEL was on, when I start next day CEL stays on for awhile but after driving long enough at a steady speed out goes the CEL. With the cooler temperatures it seems to be taking longer for CEL to go out but it does. Next day after car has cooled down, same senario.
Any help clues appreciated, thanks in advance.
