What is the reason for high fuel consumption after cleaning the throttle?
2 Answers
The reason for high fuel consumption after cleaning the throttle is that the computer was not matched and learned, so the data read by the computer is still the data before cleaning. The following is an introduction to the throttle: 1. Throttle working principle: The throttle is a controllable valve that controls the air entering the engine. After the gas enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to do work. 2. Throttle position: The throttle is connected to the air filter at the top and the engine block at the bottom, and is known as the throat of the car engine. 3. Throttle maintenance: The throttle needs to be replaced regularly, and the duration mainly depends on the quality of the air filter, the quality of the engine oil, the driving conditions of the vehicle, and other factors. 4. Types of throttle: There are four types of electronic throttles: electro-hydraulic, linear solenoid, stepper motor, and DC servo motor.
I just encountered this situation a couple of days ago. It's quite normal for fuel consumption to increase after cleaning the throttle body, mainly because the car's computer system needs time to readjust. The cleaned throttle responds more sensitively, but the engine control unit is still using pre-cleaning parameters based on carbon-clogged conditions to regulate fuel injection, causing temporary fuel mixture mismatches. Additionally, if residual cleaner wasn't completely dried during the process, sensors might misjudge air intake volume, further increasing fuel consumption. The system typically adapts within 100-200km of driving as it learns the new parameters. If the issue persists after two weeks, you should check for installation issues like missing gaskets or improperly connected intake hoses.
