Heres an old time way to test your MAF,: Sometimes the MAF gets weak and may still be working but not working right.What you have to do is to increase the air velocity flowing over the sensor. you do this by taping up the end of the air tube. so that there is only a small hole for the air to run through. make a small hole about 1/4" in diameter, make it as close as you can to the sensor, I taped up the end that has the screen on it, and made a small hole right in the center.then start up the car and see if it idles ok.If it does then the MAF is malfuctioning . if nothing changes then its ok. Try it out, its quick and easy and inexpensive..
