Sorry, won't work on modern OBD engines. The O2 sensor checks your air/fuel ratio and will correct it. Plus, 5-10 degree difference will do next to nothing as far as fuel trim. Thats also not to mention that a lean burning engine emits more NOx emissions which is nasty stuff. Factory equipped lean burn engines have a special catalytic converter to deal with this.
