What Causes Body Shaking at Low Speeds?
1 Answers
Car body shaking at low speeds can be attributed to the following reasons: 1. Severe engine carbon buildup. When there is excessive carbon deposit inside the engine, the gasoline sprayed by the cold-start fuel injector gets largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This makes starting difficult and causes shaking. 2. Ignition system issues. Poor performance of the ignition system or spark plug misfiring can lead to severe shaking during cold starts. 3. Unstable fuel pressure. Abnormal fuel pump pressure supply, incorrect readings from the intake pressure sensor, or poor sensor performance can all cause body shaking. 4. Aging engine components. Worn-out components may lead to engine mount problems, transmitting vibrations to the steering wheel and cabin, causing shaking during idle.
