You can also try cleaning it. Go to an auto parts store and buy some MAF cleaner.

jsut

ive tried that, an other thing i forgot to say, my wiring for the maf has been mixed up, my friend pulled all five wires out of the connector n did tell me

so i found out later when the truck keep running sick, saw the wires out i looked up wiring online in books, but all dont seem to work

check you fuel pressure during a drive. You may have a pump on it's way out.
