What Causes Engine Vibration in a Ford Focus?
2 Answers
The causes of engine vibration in a Ford Focus are: 1. Severe engine carbon buildup; 2. Ignition system malfunction; 3. Unstable oil pressure. Here is more information about the Ford Focus: 1. Vehicle dimensions: The Ford Focus is a compact car. Taking the 2021 Ford Focus as an example, its body dimensions are: length 4647 mm, width 1810 mm, height 1468 mm, wheelbase 2705 mm, fuel tank capacity 53 liters, and trunk capacity 511 liters. 2. Powertrain configuration: The 2021 Ford Focus is equipped with a 1.5L naturally aspirated engine, with a maximum power output of 90 kW and a maximum torque of 153 N·m. It is paired with a 6-speed manual transmission. The front suspension uses a MacPherson strut independent suspension, while the rear suspension employs a torsion beam non-independent suspension.
My Focus also had shaking issues before. After a long investigation, I found it was due to deteriorated engine mounts. These rubber components tend to crack after five or six years of use, causing direct engine vibration that makes the whole car shake. Worn spark plugs are another common cause, especially after driving 40,000-50,000 km when uneven ignition occurs. Carbon buildup can also be troublesome, particularly when the throttle body gets dirty and restricts airflow - it feels like the car can't breathe properly. It's best to refuel at reputable gas stations, as poor-quality gasoline can easily clog the fuel system. Actually, minor issues are easy to fix if detected early. I just replaced the engine mounts last week and the car immediately stabilized - the key is not to keep driving with these problems.
