Reasons for High Fuel Consumption of Volkswagen Tiguan Throttle after Cleaning

Before Volkswagen Tiguan, there was carbon deposit on the throttle. After cleaning, carbon deposits disappear, air intake increases and fuel consumption increases. Due to the long-term accumulation of carbon deposits, the throttle opening will also expand. After cleaning the throttle valve, the throttle valve opening keeps the original state. Because the original impurities acted as a part of the seal, the air intake was normal. After cleaning impurities, the air volume increases, which leads to high idle speed and fluctuation of speed indication. It may even be serious to the phenomenon of unstable idle speed or flameout.
