What Causes Engine Power Loss and Shaking?
1 Answers
Engine power loss and shaking can be caused by: 1. Damaged spark plugs - Worn electrode gaps reduce spark intensity, leading to incomplete combustion of the air-fuel mixture and acceleration vibrations; 2. Poor fuel quality - Results in inadequate fuel injector atomization and incomplete combustion in cylinders; 3. Dirty throttle body or excessive injector carbon deposits - Causes throttle sealing issues or idle control motor sticking, raising idle speed while carbon buildup induces vibrations; 4. Abnormal fuel pump pressure or faulty intake pressure sensor readings - Both can trigger vehicle shaking.
