  1. 1999, 996, c2  117k miles

     

    Due to misfiring and codes I replaced all six spark plugs and spark plug tubes as well as all 6 coil packs  While I was at it I replaced the coolant reservoir tank as it was looking pretty ugly.  everything went fairly well, however,

     

    upon startup I get an erratic/rough/low rpm idle and the following codes:

     

    P0102  mass air flow circuit low

    P1319 misfire emission related

    P1318  misfire cylinder 6 emission related

    P1315 misfire cylinder 3 emission related

    P1313 misfire cylinder 1 emission related

     

    I removed the MAS and sprayed it off with MAF cleaner  

     

     

    I'm thinking a new mass air flow sensor and all four O2 sensors need replacing??  

    Please advise.
