MAF's are extremely difficult to test. You can hook up a multimeter and read the voltages at certain RPM's. Some cars have voltage specs. But the only real way to see what the sensor is doing is to hook up a lab-scope to it. For those not in the know, a lab scope is a machine that you hook up to an electrical circuit. It has a graphing function and displays the voltage in a graph in real time, so you get an accurate picture of what the sensor is doing. Some MAF sensors send voltage signals, but most send a waveform signal. This means that the way you tell how the sensor is performing is by the heighth of the waves and the distance between the top of the waves.

do you mean an ociliscope? anyways those are extremely rare to come across and, and cost a few thousand dollars

ooookay so what waveform are u suppose to look into??

and when u unplug the injectors 1 by 1 to check if theyre going bad do you just unplug the connections??
thanks
