What Causes High Fuel Consumption and Weak Engine Power?

[OTheo]

Engine high fuel consumption and weak power can be caused by excessive carbon buildup in the injectors, spark plug issues, and problems with the intake system. Excessive carbon buildup in fuel injectors: When a vehicle's power noticeably decreases, it may be due to fuel delivery issues like poor injection or atomization. In severe cases, this can prevent the vehicle from starting. These problems are primarily caused by excessive carbon deposits clogging the injector needle valves, leading to poor fuel injection or atomization. Spark plugs: The main issues with spark plugs are excessive carbon buildup and aging. When these problems occur, they can also cause insufficient vehicle power. Intake system problems: When there are issues with the vehicle's intake system, it results in insufficient air intake. Without enough oxygen to fully combust the fuel, this not only increases fuel consumption but also affects the vehicle's power output.
