What Are the Causes of Engine Shaking in Winter?

[OKing]

Winter engine shaking can be attributed to the following reasons: 1. Mechanical faults in the engine, leading to uneven cylinder pressure across cylinders; 2. Air intake pipe leaks, excessive carbon buildup on intake valves and pipes, or excessive dirt on throttle bodies and the inner walls of intake pipes; 3. Abnormal signals or circuit faults related to water temperature and intake air temperature; 4. Excessive carbon buildup on spark plugs or damaged ignition coils; 5. Leakage in high-voltage wires or distributor caps; 6. Excessive internal carbon deposits in fuel injectors causing improper sealing or blockage. Solutions for winter engine shaking include: 1. Inspecting the engine for faults or cleaning carbon deposits; 2. Checking the operational status of spark plugs and ignition coils; 3. Inspecting circuits for potential issues.
