Why is my car losing power at low speeds?
If the pressure is low the fuel injectors will not be able to spray the correct amount of fuel into the combustion chamber and that will result in a loss of power. A faulty fuel pump will not pose problems at low speeds but when you are looking for quick acceleration you might be left wanting.
What does it mean when your car Cant pick up speed?

What causes a car to buck at high speed?
