Will fuel consumption increase after cleaning the throttle engine?

After cleaning the throttle, the fuel consumption will increase obviously in a short time, because there is carbon deposit in the throttle. After cleaning, carbon deposits disappear, air intake increases and fuel consumption increases. It can be stabilized for a period of time or the computer is reset, and then it can return to normal.

(1) Clean the carbon deposit on the electronic throttle once every 10000 km, or wait until the fault indicator lights up. After removing the carbon deposit, it will have a certain impact on the performance of the car. Take the EFI car as an example. After cleaning up the carbon deposit in the oil circuit and throttle, the car should consume more fuel. After removing carbon deposits, the driving computer needs a learning process to adapt to the working environment of automobile engines. This adaptation process is about 1000 km.

(2) Generally, the computer needs to be reset after the throttle valve is cleaned by the EFI vehicle. If you don't do it, it is likely to cause a big increase in fuel consumption. Generally speaking, the simplest reset method is to disconnect the battery cable for more than 30 seconds. I suggest you disconnect 1 min, then reconnect and run again.

(3) However, some models can't be reset in this way, and they can only be reset after being connected to the maintenance computer through the on-board OBD interface. In this case, you can only go to the 4S shop or garage to repair the computer.
