What Causes Engine Shaking and Lack of Power?

[DelNevaeh]

Engine shaking and lack of power can be caused by issues such as spark plug failure or poor fuel quality. Below is a detailed explanation of the potential causes: Spark Plug Damage: Worn spark plug electrode gaps result in insufficient spark, leading to incomplete combustion of the air-fuel mixture. Poor Fuel Quality: Causes inadequate atomization by the fuel injectors, resulting in incomplete combustion in the cylinders. Excessive Fuel Injector Carbon Buildup: Leads to shaking and power loss. Abnormal fuel supply pressure: Incorrect fuel pump pressure or faulty readings from the intake pressure sensor. The engine's function is to convert thermal energy into mechanical energy by burning fuel in sealed cylinders, pushing pistons to provide power for the vehicle. Engine maintenance methods include: cleaning the air filter; removing throttle valve sludge; and cleaning fuel injector carbon deposits.
