What to Do When the Engine Lacks Power During Acceleration?

[CamilleFitz]

Engine power loss mainly involves the following aspects: 1. Insufficient air intake: This is mostly caused by excessive carbon buildup inside the intake manifold of high-mileage vehicles, especially when there is significant carbon deposit on the back of the intake valves. 2. Poor exhaust flow: This is often due to the use of low-quality fuel in the past, leading to the formation of gum-like substances that clog the catalytic converter. 3. Insufficient fuel pressure: This is generally caused by a clogged fuel pump or fuel filter. 4. Electronic component failure: For example, a faulty intake pressure sensor or crankshaft position sensor. However, such issues can be diagnosed using specialized diagnostic equipment.
