What to Do When the Engine Malfunctions and the Car Shakes?
1 Answers
When the engine malfunctions and the car shakes, for safety reasons, you should immediately stop the car, call for a tow truck, or wait for assistance. There are three main reasons why a car shakes due to engine malfunction: 1. Poor combustion of the air-fuel mixture in the engine. When the mixture in the cylinder is too rich, the vehicle may experience knocking, shaking, and other symptoms. 2. Malfunction in the spark plugs, high-voltage wires, or ignition coils. If the ignition system is not working properly or the spark plugs are misfiring, it can cause the engine warning light to come on, leading to shaking and insufficient power. 3. Abnormal fuel supply pressure or a faulty intake pressure sensor. Incorrect fuel pump pressure or erroneous readings from the intake pressure sensor can also cause the car to shake.
