Defective Fuel Pump: The fuel pump pulls the fuel from the gas tank to the engine via the fuel lines. If the pump stops working, malfunctions, or becomes clogged, it will not supply enough fuel to the injectors. This can cause the vehicle to accelerate slowly, or even sputter and stall, especially at high speeds.
An acceleration problem is usually the result of insufficient fuel, air, or spark during the combustion process. Worn-out spark plugs or the electrical cables attached to them are one of the most common causes of cars stuttering.
Defective fuel pump or filter: Since the fuel pump is responsible for supplying your vehicle with fuel, it can cause a loss of power when it begins to wear out or when the in-tank filter becomes clogged and prevents the free flow of fuel.
