Has to do with the MAF scaling.

Could it be my maf sensor being bad? As I had random misfire 0302 code, but when I clean my maf with contact cleaner, the code will go away on it's own, and come back once a while. Could my high C range cause by a bad maf? Which under read my air going into the engine?
