Roewe 750 has unstable idle speed. What if the steering wheel sometimes shakes?
According to your vehicle condition and usage phenomenon, combined with the comprehensive analysis of current vehicle control technology and maintenance cases, this fault is caused by unclean throttle, so it is recommended to go to the repair shop for cleaning before idling matching. Because there are too many carbon deposits and dirt around the throttle valve plate and the air inlet, the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle air intake, resulting in the mixture being too rich or too thin. Therefore, ecm repeatedly adjusts the idle speed to reach the standard value, which leads to your "deviation" now.
