The fuel consumption of the vehicle is high after changing the throttle.

Why does the fuel consumption of the car increase after replacing the wearing parts?

I believe that many careful car owners will find that the fuel consumption of the car will increase after replacing some wearing parts or carrying out some maintenance. In fact, the main reasons for this situation are as follows:

First of all, it is possible that the spark plug is not installed correctly, or the spark plug model does not match. In this case, when the engine is working, high-temperature gas will slowly leak out, and the pressure in the engine cylinder will become smaller, which will lead to engine weakness and idling, and increase fuel consumption.

Secondly, the average fuel consumption is cleared. If you don't run at high speed immediately, the fuel consumption recalculated in the early stage will be artificially high. In fact, under normal circumstances, when a car runs for hundreds of kilometers, the displayed fuel consumption will fall back to the normal level.

There is also the poor quality when replacing the air filter. If the inferior air filter element is replaced, the intake resistance will increase and the engine power will decrease. In this case, not only the fuel consumption increases, but also carbon deposition is easy to occur.

Another reason may be that the throttle is not re-matched. If the throttle is cleaned during maintenance, the throttle opening will become larger, and if you forget to reconfigure the throttle, it will also increase fuel consumption.

In fact, the replacement of automobile wearing parts needs high quality. If inferior wearing parts are replaced, there are many invisible hazards besides increasing fuel consumption.
