How to Deal with Shaking During Cold Start of Outlander?

[DiAsher]

Reasons for engine shaking during cold start: 1. During cold start, the internal operating resistance of the engine is very high, so the ECU will inject more fuel, which can cause shaking at this time. 2. During cold start, the oxygen sensor has not reached its operating temperature, which can also lead to engine shaking. 3. When the engine has a misfire, it disrupts the smooth operation of the engine, resulting in shaking during cold start. 4. Some engines are particularly prone to carbon buildup. If there is excessive carbon buildup in the engine, shaking may also occur during cold start. Below are the solutions: Many engines now use direct fuel injection technology, and direct injection engines are more prone to carbon buildup. It is recommended that owners of vehicles with direct injection engines clean the carbon buildup every 20,000 kilometers. Many auto repair shops use the method of "hanging an IV bottle" to clean carbon buildup, but this method is completely ineffective and is not recommended.
