What is the suspension of Nissan nv200 refueling?

Clean the throttle valve. Dirty throttle valve 1 leads to poor acceleration, and the oil circuit is blocked. The vehicle for cleaning the oil circuit, fuel nozzle, oil circuit, oil pipe 2 and automatic transmission has started, which is normal. If you want to accelerate quickly when driving, you need to step on the accelerator deeply. At this time, the automatic gearbox will automatically downshift to increase the engine speed, and then upshift when the speed reaches a certain height. After the upshift, because the speed will drop obviously, there will be a more obvious sense of frustration. This often happens in automatic transmission models with fewer gears, such as 4-speed automatic transmission models. After the automatic transmission vehicle starts, if you want to drive smoothly, you can lightly step on the accelerator at an appropriate time, and the transmission will automatically upshift. At this time, the sense of shifting is weak; If you want to maintain good acceleration performance, you need to step on the accelerator pedal deeply, and the automatic transmission will rise to a higher gear at a higher speed, at which time the shift frustration is obvious. 3, automatic start-stop plus dual clutch gearbox, itself has this problem 4, ignition is not normal, replace the spark plug or high voltage package. 5. In many cases, the damage is not the internal valve body, but the stubborn dirt and impurities inside, especially the dirt and impurities inside the valve body gather to form a blockage, which leads to the inability to effectively adjust the oil pressure, leading to frustration, impact and slippage. At the same time, the problem of high gearbox temperature can not be ignored. High temperature will destroy the quality and friction characteristics of automatic transmission oil, increase friction and wear, and the noise of transmission will follow. At the same time, sludge (impurities or dirt) will also be produced inside the transmission (such as the valve body), which will lead to the frustration and impact of the transmission.
