[McKatherine]

The causes of engine stalling and shaking at idle speed are: 1. Dirty throttle body; 2. Excessive carbon buildup in fuel injectors; 3. Faulty engine mounts; 4. Aging engine components; 5. Ignition system issues. Solutions for engine stalling and shaking at idle speed: 1. Clean the throttle body; 2. Clean the fuel system; 3. Remove carbon deposits from the engine and fuel injectors; 4. Check if spark plugs have excessive carbon buildup and replace them if necessary; 5. Replace aged components. Idle speed refers to the engine running without load, overcoming internal friction resistance without delivering power output, maintaining the minimum stable operating RPM.
