    Yeah that's true. Didn't really think that through. Making the knock sensor change now. Pain in the asthma right now.

    depends on what code sets or what sensor fails. if maf or o2 sensor (etc) fails then yes its stuck in open loop because it NEEDS those sensors to be in closed loop. if its just an evap code setting the light then close loop is still going to function.

    good rule of thumb... for every gallon of gas burned, a gallon of water is produced.
