Welcome to the forum...
Keep in mind when a code sets its not always what the problem is, its what the system thinks the problem is....
Check the entire air intake for any blockage or cracks in the air intake after the MAF sensor....
Also check your fuel pressure to be sure its good.
Have you done any mods to the vehicle that may be preventing the vehicle from breathing good or contaminating the MAF like an over oiled K&N filter..
