Is it normal for fuel consumption to increase after cleaning the throttle body?

[LaAngela]

After cleaning, the fuel injector's spray diameter increases, leading to more fuel being injected per unit of time, which results in higher fuel consumption. This is a normal phenomenon. Below are specific methods to reduce fuel consumption: Lightly press the accelerator: When starting at low speeds, the car enters a peak fuel consumption zone. Therefore, gently pressing the accelerator during startup prevents excessively high RPMs and effectively reduces fuel consumption. Avoid high RPMs: Try to avoid unnecessary high RPMs, as fluctuating engine speeds can significantly increase fuel consumption. Regular maintenance: Change the engine oil and remove carbon deposits periodically. Avoid sudden braking: Anticipate road conditions in advance to avoid sudden braking, which not only improves driving safety but also saves fuel. For example, gradually slowing down before traffic lights and using inertia to coast.
