How to Solve Engine Cold Start Shaking?
1 Answers
Engine cold start shaking can be resolved by: 1. Severe engine carbon deposits, dirty throttle valve or excessive injector carbon buildup require timely fuel system cleaning; 2. Ignition system issues - inspect spark plugs, high-voltage wires and ignition coils, regularly check for excessive spark plug carbon buildup and replace them promptly; 3. Unstable oil pressure - visit a 4S shop to examine fuel supply pressure and intake pressure sensors. Causes of engine cold start shaking include: 1. Engine temperature too low; 2. Incorrect air-fuel mixture ratio; 3. Significant ignition energy differences among cylinders in multi-cylinder engines; 4. Faulty air flow meter signals.
