[McHaley]

Roewe 350 engine shaking may seem insignificant, but prolonged shaking can affect the driving environment and even lead to major malfunctions in severe cases. Engine idle shaking is usually caused by the following situations: 1. Intake system issues such as intake manifold or various valve leaks, excessive carbon buildup in the throttle and intake passages, idle air actuator malfunctions, or inaccurate intake volume. 2. Fuel injection system problems including injector malfunctions, incorrect fuel injection pressure, or inaccurate fuel injection volume. 3. Ignition system faults such as spark plug or high-voltage line failures, and incorrect ignition timing. Checking engine shaking requires many professional tools, such as a multimeter, exhaust gas analyzer, fuel pressure gauge, and cylinder pressure gauge. It is recommended that if owners notice engine shaking, they first conduct a visual inspection themselves and then visit a 4S shop for troubleshooting.
