Baojun 730 Disassemble and Clean Throttle Carbon Deposit

Due to the excessive carbon deposition and dirt in the air inlet, the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle intake volume, resulting in the mixture being too rich or too lean. In addition, the recent low temperature in the morning leads to poor atomization of the mixture, which leads to abnormal combustion or engine jitter after starting. Because these carbon deposits will block the idle channel, make the throttle stuck or beyond its adjustment range, resulting in low idle speed, unstable idle speed and weak acceleration. . According to the above analysis, I suggest you go to a regular repair shop for on-site inspection.
