What does it mean when your car won’t go past a certain speed?
If your vehicle speed changes without you accelerating or decelerating it, it could be low transmission fluid levels or a failing clutch. Problems with the ECU – The Electronic Control Unit, or ECU, is the brain of your car.

When I press my gas pedal it won’t accelerate?
Clogged or dirty fuel filter – A dirty filter, clogged with debris and other impurities will hinder the engine’s ability to receive the proper amount of fuel. If the fuel pump gives out or becomes clogged, it will be unable to supply fuel to the injectors and may result in poor acceleration, sputtering, or stall outs.
Why is my car dragging when I accelerate?
Dirty Fuel Injectors Dirty fuel injectors are among the most common reasons for why an accelerator becomes jerky. The dirty injector leads to your car losing power when you attempt to accelerate while at a stop and when you try to drive at a consistent speed. This is the result of an engine misfire.

Can bad spark plugs cause your car to not accelerate?

Why does my car shake and not accelerate?
When the inner CV joint is damaged or begins to fail, you will notice your car vibrating under hard acceleration. As it gets worse, the minor vibrations turn to violent shaking when under load. Damaged CV joints usually occur because of a tear in the joint boot. The only fix is to completely replace the CV joint.
Why does my car have no power when accelerating?

Can transmission cause car not to accelerate?
Transmission Problems Also, a faulty automatic transmission torque converter can cause poor acceleration from a stop. Some of the most common transmission-related problems that can lead to a loss of acceleration include: Internal automatic transmission failure.
What causes delayed throttle?
When the filter is dirty, it can cause a delay in acceleration and throttle response because when the fuel attempts to pass through a filter that is clogged or dirty, it takes far longer than it would through a clean filter.
