Santana 3000 electronic throttle vibrates at idle speed, and it feels stuffy when accelerating rapidly, and there is shooting sound when it is serious. Replace the air flow meter after further research. Oil pump cylinder line Santana 3000 electronic throttle vibrates at idle speed, and it feels stuffy when accelerating rapidly, and there is shooting sound when it is serious. Replace the air flow meter after further research. The damage of the front section of the oil pump air flowmeter should not cause the change of fuel consumption, because the amount of air passing through the flowmeter is constant. If the air intake hose in the back section is broken, excess air will enter the engine without flowmeter, and the increase of air intake will inevitably lead to the increase of fuel injection and unstable engine idle speed. Solution: The company cleans the oil circuit, and checks whether the idle motor has carbon deposit, so it should be cleaned.
