  1. Wrong MAF? pbt gf/pbt gf30

    Alfa GTV & 916 Spider
    Hi got my new maf in the post this morning and I dont think its the right one. Took the old one off and fitted the new one but it idles badly and when I tried to take it for a drive it backfired. On closer inspection my old maf is a PBT GF and the new one says PBT GF30. Guessing this is wrong...
