What Causes Loss of Power After Cleaning the Throttle Body?

[DelCamila]

Loss of power after cleaning the throttle body is generally caused by the following reasons: 1. Excessive use of cleaner: Too much cleaner sprayed during cleaning leads to an overly rich air-fuel mixture and incomplete combustion. This issue usually resolves itself after a short period of driving. 2. Improper cleaning method: Sometimes when cleaning the throttle body, the intake tract, fuel system, and catalytic converter are also cleaned, which can easily cause abnormal engine damage, catalytic converter damage, or clogging. 3. Ignition system damage: When spark plugs are about to be replaced, improper cleaning can make the engine prone to detonation, causing certain damage to the ignition system, and sometimes even damaging engine components.
