Is it normal for a car to consume a lot of fuel after clearing the throttle?

Under normal circumstances, after cleaning the throttle, the idle speed will decrease and the fuel consumption will also decrease. ..

If not, I suggest you go to the 4s shop to check it carefully.

Although it is an electronically controlled throttle, it can be adjusted, but it needs to be matched with a professional car computer.

The function of an ordinary car is not advanced enough to adjust the throttle opening through its own ECU.

The car has not been on the road for a long time, and its nose is very hot, which has nothing to do with accelerator cleaning (unless something accidentally falls into the intake manifold during cleaning ... If this happens, the engine fault light will give an alarm ...).

This has never happened before. And the specific problems can't be known until you see the car. It's hard to say yet. I suggest you check it carefully, tell the master your problem and let him explain it to you. Don't listen to the maintenance receptionist. Those maintenance receptionists are terrible.

The longer you use the car, the higher the idle speed will only be, and it will not decrease by itself.
