What Causes the Ford Focus to Shake When Starting Cold?
1 Answers
The reasons why the Ford Focus shakes when starting cold: 1. Aging ignition coil: The high-voltage wire of the spark plug aging or leaking can also lead to reduced ignition energy; 2. Inaccurate fuel-air mixture ratio adjustment: This occurs in both open-loop and closed-loop control. If the car's computer makes an incorrect judgment, its control over the fuel-air mixture and ignition timing through the actuators may have errors, thereby reducing the car's power output and causing shaking. The Ford Focus is a Class A family sedan, with dimensions of 4647mm in length, 1810mm in width, and 1468mm in height. The Focus is equipped with two engines, the 1.5L EcoBoost and the 1.5L TiVCT, and all models meet the National VI emission standards.
