What Causes Car Shaking at Idle?
1 Answers
There are several main reasons for car shaking at idle: 1. Poor combustion in the cylinders: Poor combustion results in insufficient power output, causing the car to shake. 2. Low ignition energy: The primary issue during cold starts is low temperature. When the engine temperature is insufficient, both fuel and lubricant temperatures are inadequate, requiring additional fuel injection during cold starts to meet power demands. 3. Excessive spark plug gap: With prolonged use, the ignition gap of spark plugs tends to widen, leading to decreased ignition energy. This affects power output and causes the car to shake.
