p0102 can also be for open circuit or short to ground, uncertain what you have for scan tools, but if you hook up a durametric to can view the actual signal coming from the maf. see if there is any signal at all, or a signal too low (as per definition of p0102). rev the car and see if the maf signal swings. you might have a bad wire someplace (no maf signal) or your replacement maf was bad also (low signal). good luck.
