testing the MAF sensor

[drifter sx]

is there any quick way to check if the MAF sensor is good?? i THINK [about 90% sure] that my MAF is messed up and thats why my car is doing what its doing.. and i know theres some way to check it with a voltmeter and such but i dont have one. i ordered a new MAF, and i have the old one sitting in my hand.. im picking up the new one later tonight. but i dont wanna pay $100 for something i might not need.. any quckin easy way to tell if the MAF is bad??

Just unplug it when the cars running,And the engine sould turn off.If it stays on the MAFS probley no good.

If I were you I'd probably pay $10-$15 for a cheap multimeter and test it. Or get a better one if you like. A multimeter will always be good to have around; an extra maf that you didn't need isn't good for much.
