Default fuel trim fault

I keep getting "fuel trim fault" for both banks

No air leak is apparent, and fuel pressure, plugs, wires check out fine

Only happens about once per week

Also, engine runs perfectly...

Has anyone else ever had this problem?

What is the diagnostic trouble code (DTC) you're getting?

MAF sensor? Do you use K&N oil filled air filter?
