What Causes Shaking and Lack of Power When Climbing Hills?

[AugustFitz]

Causes of insufficient power when a car climbs hills are as follows: 1. Fuel system issues. The fuel system is a common problem area in cars. Insufficient fuel entering the combustion chamber may be caused by clogged fuel injectors, fuel leaks, reduced fuel pump performance, or a blocked fuel filter. 2. Poor fuel quality. If using counterfeit or substandard gasoline with excessive impurities, when the engine is running, the poor-quality gasoline fills the fuel supply system. Components with small holes or filtration functions, such as the fuel pump filter, fuel filter, and fuel injectors, can easily become clogged by impurities in the low-quality gasoline, leading to poor fuel supply and reduced engine performance. 3. Faulty ignition coil. If the ignition coil is damaged, one cylinder may fail to ignite and operate properly, resulting in insufficient power due to a misfiring cylinder and accompanied by engine shaking.
