Well my buddy has the HPTuners VCMScanner on his laptop and i had him clear the codes and run it again after a little drive. the MAF code came up in like 5 seconds. it stayed at like .23lb/min no matter where the throttle was, so im assuming thats what is wrong. no?

Those MAF readings should change with the amount of airflow moving through the intake.
Before we send you off spending over a 100 bucks and does for a new sensor, try this test to make sure your MAF is getting power.
