The fuel consumption of the car after cleaning the throttle is obviously high?
Because the throttle valve was cleaned and the relevant matching treatment was not done, the computer detection program still adjusted the fuel injection amount according to the original throttle valve calculation. Ordinary cars will adapt to this possibility after driving for a period of time.
Because the throttle has not been cleaned for a long time, the position of the throttle and throttle arm is worn too much. At this time, after cleaning the throttle, the gap is even bigger.
If the throttle valve is too dirty, the intake branch pipe and the valve root must be dirty. For a single car, if it is not washed, it is in a state of balance. Once the throttle is washed, the equilibrium state is broken, resulting in higher fuel consumption after the throttle is washed.
