- a - take the vehicle temperature to 90°C (194°F) or above.
- b - front cylinder throttle valve correction between - 60 and 60.
- b - rear cylinder throttle valve correction between - 60 and 60.
- c - potentiometer 1 front throttle valve value is 0.5 or above.
- d - potentiometer 1 rear throttle valve value is 0.5 or above.
- e - the difference of throttle valve correction values between the front and rear cylinders should not exceed 0.6.
