Default 1998 Maxima MAF

I have received a recurring 0102 ECM code (obtained directly from ECM by flashing MIL, not scan tool) indicating a faulty MAF. The symptoms are in agreement - stumbling, occaisional stalls, lack of power. Replaced air filter and cleaned MAF wire with "MAF Cleaner" spray to no avail. Dealerships have indicated that some sort of ECM reflash might be needed and also a 'relearn'. But I have gotten conflicting stories on this. Can anyone tell me 1) if an ECM update would be upon replacing an ECM in a 1998 Maxima, and 2) how to perform the relearn procedure. I have a service manual for the vehicle.19

Idle Air Volume Learning Procedure
1) Start engine and warm it up to normal operating temperature.
2) Turn ignition switch OFF and wait at least 10 seconds.
3) Confirm the accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
4) Repeat the following procedure quickly 5 times within 5 seconds.
1) Fully depress the accelerator pedal.
2) Fully release the accelerator pedal.
5) Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL goes off.
6) Fully release the accelerator pedal within 3 seconds after the MIL goes off.
7) Start engine and let it idle.
8) Wait 20 seconds.
9) Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications

i think on the lder gen maxima you can manually reset it by accesing the ecm. also unpluggin the battery for a few hours should reset the computer
