My car Kia Lion ran 2.0 automatic transmission and ran 23,000 kilometers. Recently, I encountered slow speed increase, high speed and deep throttle, but I couldn't lift the high speed. 140, the car is in poor condition. 1, change to another gas station. I have two identical gas stations here. The oil in one gas station accelerates the meat, which is noisy, while the oil in another gas station accelerates quickly, and the throttle is sensitive to noise.

2. Clean or replace the air filter. If the air filter is too dirty, it will lead to insufficient air intake, insufficient combustion, decreased power performance and easy carbon deposition. Wash it quickly.

3, clean the throttle, 23,000, if it is not washed, it should be washed. Pull the car at low speed and high speed (about 3000) after maintenance.

The spark plug needs to be replaced. It is better to get a better component like this.

The rest should be no big problem. 23 thousand is still a quasi-new car.

If you drive everyday, in my experience, if there is a certain slope but it is difficult to see with the naked eye or the wind speed is very high, it should be normal for the engine to idle at high speed.
