How to maintain high engine speed after Toyota Yizhi loosing oil?

1. It may be that the position of the vehicle accelerator switch is inaccurate, which causes the engine speed to increase when the driver releases the accelerator pedal. 2. If there is too much carbon deposit in the engine, or the position of the fuel nozzle changes due to carbon deposit, the number of revolutions of the engine will increase after the driver releases the accelerator pedal. 3. It is also possible that the vehicle exhaust system is blocked, which makes the engine idling unstable, thus loosening the accelerator pedal and increasing the engine speed. 4. If the vehicle oil pressure is unstable, after the driver releases the accelerator pedal, the vehicle speed will increase and the vehicle body will shake. When the owner encounters the above phenomenon, he needs to drive the vehicle to the garage or 4s shop in time, and the vehicle will be overhauled by professionals to ensure that the vehicle can be used normally.

Hello, you want to see if this is the reason.

When driving at high speed, the engine speed is 2600 and the vehicle speed is 120 km. At this time, release the accelerator pedal, and the engine speed is still 2600 rpm, so I can't get down.
