How to Solve the Idle Vibration of Tiggo 3?
4 Answers
Tiggo 3 idle vibration solution: First, adjust the idle speed. If the problem persists after adjustment, check whether the idle jet and idle air jet are blocked. If blocked, clean them with gasoline or acetone and blow them through with compressed air. If not blocked, stabilize the engine speed at a certain level and check for air leaks at the intake manifold or the middle and lower gaskets of the carburetor. Taking the 2020 Tiggo 3 1.5L Manual Million Global Edition Fashion model as an example: its body dimensions are 4420mm in length, 1760mm in width, and 1670mm in height, with a wheelbase of 2510mm. The body type is a 5-door, 5-seat SUV, with a naturally aspirated intake form, a maximum horsepower of 116ps, and a maximum torque of 143nm.
I've been driving a Tiggo 3 for several years and often encounter idle vibration issues, especially during cold starts or when stopping at red lights—it feels like the entire cabin is shaking. This is usually caused by excessive carbon buildup in the engine. A dirty throttle body affects air intake efficiency, making the engine run unevenly. The solution is to first try cleaning the throttle body yourself. Just buy a specialized cleaner and spray it inside—it's simple and saves money. If the vibration doesn't improve, check if the spark plugs are worn out or old. Replacing spark plugs is easy, and a new set can improve ignition. Also, inspect the ignition coils and fuel filter, as these are common issues. If it's a fuel pump or vacuum leak, you'll need to visit a professional shop—it's not a DIY fix. Addressing it early saves fuel and extends engine life—don't wait until the vibration gets worse. I usually use higher-octane gasoline and additives to prevent carbon buildup, which works well.
In daily vehicle use, I've noticed that the idle vibration in the Tiggo 3 is often caused by carbon deposits accumulating on the throttle body and intake passages, leading to restricted airflow. It's recommended to prioritize cleaning these areas, and using a cleaning agent for DIY treatment is quite effective. If the vibration persists after cleaning, it might be due to faulty spark plugs—check the electrode gap or replace them directly. Also, inspect whether the ignition coils have any leakage issues or if the fuel pump pressure is sufficient. Additionally, if the engine mounts are aged and loose, they can amplify vibrations; a gentle press can confirm this. After conducting these preliminary checks yourself, if no issues are found, it's advisable to visit a repair shop to use a diagnostic tool for checking data streams to identify the core fault. Regular maintenance, such as cleaning the intake passages every 5,000 kilometers, can prevent most vibrations, ensuring smoother and more comfortable driving while also reducing fuel consumption.
I previously dealt with the idle vibration issue on my Tiggo 3 myself, and it was quite simple—start with the spark plugs. Pull them out and check the electrodes; if they're blackened or worn, try replacing them with a new set, as this is the most common root cause. Also, clean the throttle body by spraying a dedicated cleaning solution inside to remove dirt. Be careful not to touch the sensors during the process to avoid triggering the fault light. If the vibration persists after addressing the spark plugs and throttle body, it might be due to poor contact in the ignition coils or a clogged fuel system. In that case, a visit to the 4S shop wouldn’t be too late. Doing it yourself can save some money. For maintenance, opt for higher-quality engine oil and fuel additives to prevent carbon buildup, which can affect idle stability.
