Mass Air Flow sensor (MAF) replacement 98 Maxima

[max98]

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.

People at autozone can reflash it for you i believe or you can just unplug the negative terminal on the battery for awhile
