Hi Matthew,

Here is a video on how to check the MAF with a meter:

Also, here is a guide on how to clean it to hopefully try and avoid how to replace it:

As for resetting the computer after you replace a sensor, I assume you mean you want to clear the codes. If this is the case, then you will need a scan tool. Some people will just disconnect the battery for 10 minutes and this will force the control modules to retest due to the memory being erased because the modules can't retain the memory for this long with no voltage. However, this will also wipe out all of the other memory including the radio settings and adaptive numerator information for the engine. So you will need to reset these things and drive the vehicle until it relearns the engine data again.

Here is a guide on the more common causes of stalling at idle because I am not sure the MAF will cause the vehicle to just shut off:

Please let me know if you need more information. Thanks
