There is a serious retrogression in the rapid acceleration above 60. What's going on here? Solve it! ?

The long distance to my hometown two days ago was1450km. The rapid acceleration above 0.60 has a serious retrogression. What's going on here? Solve it! Lei Ling 1.2T will automatically pay a daily fine of 38,000 kilometers for two years and 1450 kilometers for the first two days. The rapid acceleration above 0.60 has a serious retrogression. What's going on here? Solve it! Lei Ling 1.2T automatic sunning vehicle, with a two-year 38,000 kilometers, may be caused by dirty gearbox oil, or high long-distance oil temperature, or the rapid acceleration and continuous downshift do not match the engine speed. If you often drive at a high speed of more than 38,000 kilometers, you can change the gearbox oil to avoid serious wear of the clutch gear. This is the high voltage belt (ignition coil). Where are you going to the 4S shop? Free car inspection. A few days ago, I was over 60 and accelerated several times. It is good to reach 80, because sometimes you have to overtake or something. We must refuel urgently. Let's go In this case, it is most likely that one of the high voltage clamps (ignition coil) is broken, and I will go to SS to change it, because I have also appeared. 60 rapid acceleration has setbacks. Later, it was fine after it was changed. 1. Check the throttle: Check the throttle: 1. First, check whether it is stable from the idle speed. 2. Then, step on the accelerator to 4000 rpm in neutral, and release the accelerator pedal to see if the accelerator falls back smoothly. 3. Finally, check whether there is a fault code, and clean the lower throttle, nozzle and intake branch pipe after normal driving for 4 kilometers. 2. Check the choke: the choke is divided into two situations: 1. Mechanical blockage or blockage 2. Circuit failure. In the first case, it can be disassembled and put on the syringe cleaner for experiment. In the second case, you can read the fault code through the decoder, you can also hear the working sound of the injectors one by one through the stethoscope, and you can also measure whether the control signal and coil of each injector are normal. 3. Check the air inlet: Check the air inlet method: Remove it and blow the air inlet with your mouth. If there is air leakage, it means it is broken, and the vehicle will not start until it is ignited for more than two times; If there is no air leakage, the carbon canister solenoid valve is in good condition, and find other reasons. The carbon canister is usually installed between the fuel tank and the engine. Because gasoline is a volatile liquid, the fuel tank is often filled with steam at room temperature. The function of fuel evaporative emission control system is to introduce steam into combustion and prevent it from evaporating into the atmosphere. The storage device of activated carbon tank plays an important role in this process. 4. Check the spark plug: check whether the spark plug gap meets the requirements. The specified value of spark plug electrode gap is 0.7 ~ 0.8 mm, check with a feeler gauge. If the spark plug electrode gap does not meet the requirements of compliance setting, it should be adjusted. The method of adjustment is. Tap the side electrode lightly to make the gap within the specified value. 5. Check the ignition coil: Check whether the ignition coil is in good condition can be done on the machine. @20 19
