Code P1178

I'm getting code P1178 "AMFR Correction At Maximum Positive Value"... So I'm guessing it has something to do with my fuel injection, maybe fuel injectors or something. The truck is running rich.

Just wondering if any of you all have had your truck throw this code and what it was...

Thanks

AMFR stands for "Air Mass Flow Rate". Do you have any leak in any of the corrugated pipes? Is it possible that your MAF sensor is on its way out (do you have one you can swap to check)?
