    did you change the plugs for correct ones for your car ? NGK? coils are OEM ?
    one more thing it's recommended to change all the coils in the same time

    Hi thanks for replying..
    i change 2 of the coils as in my saab are individual ones not the whole cassette. also i replace only 2 used ones from ebay but tested by my mechanic and are ok.
    spark plugs he replaced with better ones? cant remember the brand.
    my error 1312 is for colinder 1 and 2 so new plugs and coils

    Thanks!!!

    Check to see what spark plugs they put in as Bruno mentioned.

    Hi guys thanks for the reply, according to my mechanic the 4 new plugs apparently are better than the old ones i dont know the brand of these new ones.
    but also why does the car only "caugh/limps a bit" in the morning when is cold but after acouple of minutes when engine warms up a bit the car runs great?
    i can get this is only in the morning when car is cold but after a couple of minutes its fine.
    could that be the plugs? even if they are new?
    thanks
