What causes a Nissan Altima to lose power?

What causes a Nissan Altima to not accelerate?

In some Nissan vehicles, the fuel filter may be dirty or, even worse, clogged. This means that the vehicle is not getting enough fuel into it to allow for that increased acceleration to take place. If the filter is clogged, it may not allow enough air to flow in, leading to problems with acceleration.

Why does my Nissan Altima stall when I accelerate?

The car will stall if the valve is too clogged or when it finally fails. If, while holding the accelerator pedal down, a small amount of pressure keeps the car running at a stop, the idle control valve may require attention. In most late model cars, this problem will usually trigger the Check Engine light.

Why does my Nissan Altima whine when I accelerate?

Low Transmission Fluid: For both manual and automatic transmissions, the primary cause for whining when in gear is low transmission fluid.
