I started to set my air flow / tower setting by reading the duty cycle and found that it would not move off 50%, indicating the O2 sensor is bad...RIGHT? SO until I can get the sensor in, can you set the co correctly by reading EHA voltage instead or will the bad O2 sensor also effect the EHA reading?
