Why does the New Santana's idle speed increase automatically when the clutch is pressed?

[VanKimberly]

New Santana's idle speed increasing automatically when the clutch is pressed is caused by excessive carbon buildup in the idle valve or the system's throttle compensation. Below are the detailed explanations: Excessive carbon buildup in the idle valve: It is due to excessive carbon buildup in the idle valve or poor performance of the valve itself. High idle speed naturally leads to increased fuel consumption, which is mainly related to unstable RPM. Additionally, when the engine's fuel supply is constant, the lower the load, the higher the RPM. When the clutch is pressed while driving, the engine has no load at all, so the RPM naturally increases. Automatic throttle compensation by the system: After pressing the clutch and releasing the throttle, the computer automatically provides throttle compensation to prevent the engine from stalling, causing the engine's RPM to rise. Generally, the RPM does not increase significantly. If the RPM rises excessively, it is recommended to visit a 4S shop to check for potential engine computer faults.
