you may have fried your maf. Proper way to check maf is to take the voltmeter - to the black maf wire (ground) and check the two other wires. One wire should have a 5v constant, and the other should be about .5 volts. The .5 volt wire SHOULD show a rise in voltage when you open the throttle. If none of this is showing, and you get battery voltage, then you know your MAF is definitely fried. You might want to check the ECU as well. Tap the ecu pins (for MAF) and make sure the ecu is sending the 5 volt reference and receiving a signal.

diagnose it correctly, don't just go buying parts. Unless you like doing that, then go ahead.
