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.

Accepted Answer: a. Acceleration is in the direction of motion, when you are increasing the speed of the car moving along a straight line. ... Acceleration is against the direction of motion, when brakes are applied to the car in motion.

An acceleration problem is usually the result of insufficient fuel, air, or spark during the combustion process. ... A deficient spark plug causes the engine to misfire, making your car jerk when you accelerate. The engine may also be much noisier than it normally is, sounding more like an aeroplane taking off than a car.

If there is no fluid, there is no hold, the gears cannot spin and therefore the car won't be able to move. If your vehicle does get to the point of having no transmission fluid, you will likely also be looking at extensive repairs or even a full replacement of your transmission.

Scoring and grooves in a rotor can impede its capacity to slow the vehicle, as well as cause vibration and pulsation that can be felt in the pedal. Plus, when the pedal no longer interacts with the brake rotor, the ensuing vibration may make it feel like the car will not stop at all.

Car stalls while driving One of the first symptoms of an issue with the ignition switch is a vehicle that suddenly stalls while the engine is operating. If the ignition switch fails while the engine is operating it may cut off power to the ignition and fuel systems, which will cause the engine to stall.

Technically, you can (usually) drive slowly when in a fail-safe mode—or when engine power reduced is illuminated on the dash. However, doing so is not recommended. It is best to tow your vehicle to the nearest repair facility, as driving at extremely low speeds can be dangerous.

There are many reasons why your vehicle may be losing power, especially when accelerating. Some of these common causes are: Mechanical problems such as: Low compression, clogged fuel filter, dirty air filter, clogged Exhaust Manifold. ... Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.

No, you can't drive a car with broken rotors and no brake pads. The car is a mass of one or more tons of moving metal and the only thing that gets it to a standstill are intact rotors and pads. If there are no brake pads, there is nothing that will create enough friction to slow down the car.

When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle. This can include stalling when coming to a stop or very low idle after starting, or even stalling if the throttle is quickly pressed (resulting in the throttle body plate opening and closing very quickly).

Engine Stalling or Misfiring Erratic engine behavior may also indicate a bad or failing ECM. A faulty computer may cause the vehicle to intermittently stall or misfire. The symptoms might come and go and not appear to have any sort of pattern to their frequency or severity.

People think, “If the acceleration is negative, then the object is slowing down, and if the acceleration is positive, then the object is speeding up, right?” Wrong. An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down.

More often than not, when a car jerks when accelerating at low speeds, it's because there's a problem with the spark plugs in it. A simple tune-up should be able to stop the jerking once and for all. But there could also be a problem with the air intake system or with the catalytic converter.
