check the code, if the leak is at the header gasket, i would think that air could get sucked in which would go through the header. Once it hit the o2 sensor, the sensor would tell the computer that there was more oxygen in the exhaust(aka running lean) so the computer would try to compensate by adding fuel. Just a thought.
