Angry code 48 and occasional stalling at stoplights

I am getting a code 48, which is the mass air flow code. What do I do to figure out whats going on here. Thanks, Michael

Do you have driveability issues? If so try disconnecting MAF and see if they clear up. You can also try tapping on it whith a screwdriver. You can get replacement MAF's for about $149.
