Clean air filters and fuel injectors will reduce the strain on your car. An engaged emergency brake causes the brake to drag slowing down your car. Disengage the brake to solve this issue. Sometimes acceleration problems are just because of low fuel or poor quality of fuel.
Why does my car feel like it’s hard to accelerate?
Among the causes of poor acceleration are clogged fuel injectors and/or inadequate fuel pressure/volume. When an injector is clogged it can degrade the performance of the vehicle and the car may accelerate slowly or feel that it does not have enough power.
What causes a car to miss on acceleration?
The most common cause of an engine misfire when accelerating is worn-out spark plugs. When spark plugs are suffering from excessive wear, they don’t ignite the fuel in the piston cylinder when they are supposed to. This can also be caused by fouled spark plugs, a cracked distributor cap, or bad spark plug wires.

Not being able to shift is a direct result of having low transmission fluid. Slipping Gears – On the flipside, slipping out of gear is another side effect of having low transmission fluid. For example, you may be maintaining your current speed, then suddenly feel your vehicle downshift or shift to a higher gear.
What are the symptoms of low automatic transmission fluid?
Sudden up and downshifts, spikes in RPMs before shifting, strange grinding noises, and erratic shifts are also characteristics of this problem. All of these are low transmission fluid symptoms and indicate that you’re at risk of overheating.
How does a car act with no transmission fluid?
Low-quality transmission fluid – or driving without transmission fluid altogether – can cause a number of problems such as transmission failure, gear slipping, a hard time shifting, and a few more issues.
