My Reiz cleaned the throttle, but the fuel consumption went up. What happened?

The best answer is 2011-01-kloc-0/813: 49 First, there is no carbon deposit in the engine cylinder after cleaning the throttle. It's clean, but the gap between the cylinder, piston and piston ring is larger than before cleaning. Not as tight as before, it will affect the engine compression ratio (cylinder pressure) to a certain extent, and it will also cause the fuel consumption to increase (the error should be 1-2 liters/100 kilometers). Second. After cleaning the throttle, it is recommended to adjust the ecu of the engine, initialize and re-match the engine. After driving for about half a month, or the mileage is about 1000 km, the fuel consumption should be reduced and return to normal. Your car is 10 year old, so the error will be bigger. It is not recommended to clean the throttle and injector according to the prescribed mileage. Doing these repairs as little as possible is not good for your car. Best advice: If you can't fix it, don't fix it. Make do with it. The more you fix it, the more problems there will be.
