I would suggest looking at the mixture adaptation numbers.
Ideally they sould be very close to 1.00.
If they have gone to 1.25 or are heading in that direction replacing the MAF will usually cure the problem.
MAFs (mass air flow sensors) are common issues, and may be defective without a CEL.
Possible:
* Bad spark plugs.
* Bad MAF.
* Bad O2 sensor.
* Tired engine.
