What is the solution for Emgrand idle vibration?
2 Answers
It may be related to the quality of the gasoline used, or the idle speed is unstable or too low. It is recommended to clean the throttle body, and after cleaning, reset the throttle position. It could also be caused by excessive engine carbon deposits, which require cleaning with a specialized carbon cleaner. If the vibration is severe and the engine fault light is on, it is recommended to go to a nearby repair shop to use a computer to check the fault codes and data stream. Check whether the engine has a misfire, whether the spark plugs are worn out, whether the ignition coils are aged, and whether there is any leakage in the cylinder wires.
After driving for so many years, my Emgrand has also had the issue of idle vibration. The most common causes are aging spark plugs or carbon buildup. Replacing the spark plugs usually solves the problem. If the fuel injectors are clogged, cleaning them can restore normal operation. For heavy carbon deposits, using additives or cleaning the throttle body can help. Worn engine mounts can cause severe shaking, and replacing them will eliminate the issue. A dirty or faulty throttle position sensor can also lead to unstable idle; cleaning or replacing it should fix the problem. Sometimes, a dirty air filter affects airflow—try replacing the filter. Always use fuel from reputable gas stations and avoid low-quality gasoline. If you're not confident in your DIY skills, it's best to visit a 4S shop or a reliable repair shop for diagnosis instead of tinkering on your own. Regular maintenance is key—check these components every 5,000 kilometers.
