Check the wiring going to the mass airflow sensor as well as the plug that plugs into the mass airflow sensor. You may have a bad connection. HTH. -Jim

If you could give the actual code (ex: p0303) that would help more. Most maf codes are from vacuum leaks or unmetered air entering the system. I've seen many maf codes, most end up being something else.
