What is the impact of Buick Hideo's dirty throttle?

Hello. First of all, if you are a Buick Hideo of 18 19, you should use 1.0t and 1.3t engines. Because both engines are in-cylinder direct injection, there is more carbon deposition in the intake pipe. Then the intake air quantity of the engine is inaccurate. If too much carbon deposit causes the throttle valve body to jam, the control is not sensitive. Will lead to engine idling jitter. If there is only a slight carbon deposit. That doesn't matter much. I hope it helps you.
