What should I do if the speed can't be raised after Nissan adds a new throttle?

Hello, the "meat delivery by accelerating car" is mainly caused by insufficient oil supply in the engine. Generally speaking, it may be due to the following reasons: First, the fuel injector may be blocked, resulting in engine idling jitter, increased fuel consumption and weak acceleration; Second, the blockage of the three-way catalytic converter will also increase fuel consumption and reduce power. In addition, if you don't pay attention to maintenance and don't replace the hollow core for a long time, it will also cause speed increase and obesity, but this situation is rare.
