The fault light of Buick Hideo dithering engine is on.
1.? The most common thing is that dirty throttle or faulty throttle will lead to idle jitter. The main reason of dirty throttle is that there is carbon deposit at the joint between throttle valve plate shaft and throttle body, which leads to inaccurate throttle opening, so idling jitter will occur. So we can clean the throttle first. If it doesn't shake after cleaning, it means the throttle is dirty. If it still shakes after cleaning, it may be that the throttle assembly is damaged and the throttle needs to be replaced. Just a reminder, because all vehicles use electronic throttle now, you need to learn idle again after cleaning the throttle.
2.? Poor gasoline quality leads to poor atomization effect of fuel injector, and insufficient combustion of mixed gas in cylinder will also lead to idling jitter. It is recommended to use high-grade gasoline after using this box of gasoline and do a fuel system cleaning.
3.? The spark plug does not ignite, which leads to one or more cylinders not working, and also leads to idle jitter. Check the spark plug If the ceramic part of the spark plug is cracked, also check whether the ignition module is normal.
