Mass Air Flow Code when Accelerating

I get a P101 Engine Code sometimes when I'm on the Freeway and I accelerate rather hard, often when pulling a trailer but sometimes just accelerating up a hill. This code indicates a bad reading from the Mass Air Flow Sensor. It goes away after awhile and I don't have any performance issues; runs fine.

I cleaned the sensor using MAF cleaner but I still occasionally get the code.

Do you think this is normal? Do you think I need to replace the sensor? Again, I don't see any performance issues.

Thanks

Yes I have a stock air filter and not K&N style. I will give it a more careful inspection and check out the links you provided.
Thanks!
