Re: Resetting Service Engine Soon Light
to reset any service light all you have to do is disconnect the battery and reconnect... i wouldn't mess with the ecm fuses because that controlls your air/fuel ratio, timing, thp, ect the computer accually learns the type of driver you are(if your the main one) and shifts controlls over that way, so if your a throtal jocky then it prolongs shift points for better perfomance, if you are a gas saver then it short shifts to increase gas miliage.
hope I helped
