What Causes the Zotye T600 to Shake When Cold?
3 Answers
The reasons for the Zotye T600 shaking when cold are: 1. Excessive carbon buildup in the throttle body, fuel injectors, and intake passages; 2. Mechanical failures such as ignition coils, spark plugs, or fuel injectors leading to cylinder misfire; 3. Insufficient power due to low oil pressure or cylinder pressure; 4. Substandard fuel quality; 5. Damaged or excessively dirty idle control valve; 6. Air intake manifold leakage; 7. Damaged engine mounts or cushion pads; 8. Oxidized or low-grade engine oil. The Zotye T600 is Zotye's first mid-size SUV model, offering a total of 9 different variants. It is equipped with either a 1.5T or 2.0T engine. The 1.5T engine is paired with a 5-speed manual transmission, while the 2.0T engine comes with either a 5-speed manual or a 6-speed dual-clutch (DCT) transmission.
As a long-time owner of the Zotye T600, cold engine shaking is quite common, mainly due to ignition system issues such as aging spark plugs or carbon buildup causing poor ignition, which leads to unstable combustion during cold starts. Another common cause is fuel system supply problems, like clogged fuel injectors resulting in uneven fuel delivery at low temperatures. Additionally, worn engine mounts can increase vibration, making the body shake more noticeably. Moreover, a dirty air filter in cold weather affecting air intake can also easily cause shaking. It's recommended to first check the spark plugs yourself and replace them promptly; if the shaking persists, clean the fuel lines and injectors. Regular maintenance can significantly reduce such issues—don't overlook periodic oil and air filter changes.
Having worked in car repair for over a decade, I've encountered many Zotye T600 owners reporting cold start vibrations. In most cases, it's due to ignition system failures, such as excessive spark plug gaps or damaged ignition coils, leading to inaccurate ignition. Fuel system issues like insufficient fuel pump pressure or carbon buildup in injectors can also cause uneven fuel supply during cold starts, resulting in vibrations. Air system faults, such as vacuum tube leaks, can imbalance the air-fuel mixture. During troubleshooting, use a diagnostic tool to check error codes for targeted repairs. Regular maintenance, like replacing spark plugs every 20,000 kilometers and cleaning the fuel system, can prevent this issue. Ignoring it may affect idle stability and increase fuel consumption.
