What are the effects of a dirty car throttle on the vehicle?

[DelOscar]

The effects of a dirty car throttle on the vehicle: 1. Difficulty starting or failure to start; 2. Abnormal idle conditions, such as unstable idle speed or fluctuating idle (too high or too low); 3. Weak acceleration or inability to speed up, such as throttle sticking; 4. Failure to meet emission standards; 5. Abnormalities like jerking or surging; 6. Obstruction when accelerating, such as throttle body sticking or idle valve flipping obstruction. Therefore, it is necessary to clean the throttle regularly. When cleaning the throttle, it does not need to be disassembled, but the intake sealing parts must be thoroughly cleaned. The idle motor must be removed to be cleaned properly. It is important to note that after cleaning the throttle, the throttle opening must be reset. Otherwise, the car's computer will still remember the opening when there was carbon buildup, and if not reset, the engine may experience unstable idle speed or excessively high RPM.
