How to Solve the Jerking Issue When Accelerating in Eado?
2 Answers
Excessive carbon deposits on the throttle valve, fuel injectors, and intake manifold can cause jerking sensations. The solution is to clean the carbon deposits. Poor fuel quality leading to incomplete combustion can also cause jerking. It is necessary to switch to higher-quality fuel. Faulty spark plugs or ignition coils can result in jerking. Replace the spark plugs and ignition coils.
My Yidong also experienced jerking during acceleration, feeling unstable and unpleasant to drive. I first checked the spark plugs myself and found severe carbon buildup. After replacing them, the issue persisted. Then I tested the fuel filter, as clogging can cause uneven fuel supply. Cleaning it improved things slightly. The most troublesome part was the aging ignition coils, which affect ignition timing and cause jerking. Since I'm not familiar with electronic systems, I asked a car-savvy friend to help scan with an OBD scanner, which revealed a faulty throttle position sensor with erratic data. After spending a few hundred to replace it, the jerking completely disappeared. Don't overlook these basic components during maintenance, especially for older cars. Spark plugs should be replaced every 30,000 km to prevent major issues. If you experience jerking, address it promptly for smoother driving.
