  1. Running rich, don't know where to start...?

    5th Gen

  6. Burning Rich. faulty injectors??

    3rd Gen
    hey guys so after researching the forums and not finding any answers i feel its time for me to open a new thread. i own a 1990 SR B21a1 2.1L, with 325'000 k's on it. right now im getting 460 km's to a full tank, (using regular gas) mid grade seems to give me worse gas mileage. normal? anyway i...
