443 is a evap code http://www.obd-codes.com/p0443

102 is low voltage tot he maf check the fuse box under the hood for # 21 to be blown iirc, its labeled ing or the wires to the maf's plug are bad. look for cracks or missing insulation, if you see bare wire the pig tail is shot. it needs to be cut off and replaced.

only buy a maf for your year car. 97-98, 99-00, 01-03 those are your years of the same maf, you cant mix em up.
