FAQs
There are several causes for your car to lose power significantly while accelerating. The most typical causes of a car not accelerating while driving include a faulty sensor, contaminated fuel or air filters, or a faulty timing belt. Generally, this isn't something you should ignore.

Factors Affecting The Performance Of Your Car
Various external and internal factors affect a car's performance. These can range from external factors like road conditions and weather to internal factors like engine maintenance and the way you drive.
What does it mean when your car sputters while driving? ›
If the fuel amount is too much or too little, the engine may begin to sputter. Your mass airflow sensor tells you how much air is in the engine. Just like the oxygen sensor, the engine will sputter if there is too much or too little air. Spark plugs are an integral part of your engine.
Why is my car sputtering and jerking when I accelerate? ›
Worn-out spark plugs, or the electrical cables attached to them, are one of the most common causes of stuttering. A deficient spark plug causes the engine to misfire, making your car jerk when you accelerate.
What makes a car accelerate smoothly? ›
To ensure your car accelerates properly and avoid acceleration issues, regular maintenance is a must. This includes checking the spark plugs for wear or corrosion and replacing them periodically. Additionally, you should also check and replace the fuel filter regularly to keep it clean and functioning optimally.
What are the three cases for acceleration? ›
Answer and Explanation: There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction. Imagine a racecar that's traveling in a straight line. If it changes velocity (speeds up or slows down), then it's accelerating.
What are the key factors affecting performance? ›
Communication and collaboration – These are two key factors associated with employee productivity at the workplace. A constant flow of communication is necessary to keep teams updated, informed, and engaged. Lack of communication results in silos, therefore reducing employee productivity.
What are the three factors which affect their performance? ›
Having the right attitude, being confident and managing pressure are all-important. So is having the right level of energy and fitness to do a great job. Great performers have support teams and they know how to use them. They know the emotional part of performance is critical.
What is the factor affecting motor performance? ›
Motor performance is affected considerably by the quality of input power, that is the actual volts and frequency available at motor terminals vis-à-vis rated values as well as voltage and fre- quency variations and voltage unbalance across the three phases.
How do you diagnose engine sputtering? ›
If your car engine starts sputtering, don't panic! First, perform a visual check for any obvious issues, like disconnected wires or visible leaks. Think back to when you last replaced certain components, like spark plugs or air filters; it might be time for a change.
A sputtering engine is a sign of a lean fuel mixture in the combustion chamber. This can happen if you have a clogged somewhere in the fuel system that impedes the delivery of fuel into the chamber.
Why does my car stutter at idle? ›
A rough idling engine can be caused by spark plugs or spark plug wires. Spark plugs use the electrical current received from ignition coils to ignite the air/fuel mixture within the combustion chamber. A plug that is damaged or installed incorrectly can result in fuel being burned at an inconsistent rate.
Why does my car shudder when I idle? ›
Common Causes of a Vehicle Shaking When Idling
Sometimes power loss. This is due to inadequate combustion in the engine cylinders. An engine misfire can also be caused by worn spark plugs where only some of the cylinders fire correctly. This leads to an uneven running engine that shakes at idle.
How do I fix my car from jerking? ›
Fixing a car that jerks when accelerating is often a simple matter of replacing dirty or worn-out parts, such as spark plugs, oxygen sensors, mass airflow sensors, or throttle position sensors.
Why does my car shudder when I accelerate? ›
A common issue is unbalanced tires. When your tires are unbalanced or even bubbled, you could also experience shaking when you accelerate. It could be a bent axle or driveshaft. The driveshaft also connects the engine to the wheels and axles of the rear wheels.
Why does my car feel like it's lagging when I accelerate? ›
A car that hesitates when accelerating is likely to have an engine issue—like a clogged fuel filter or broken fuel pump—although it's also possible that there's something wrong with the transmission. Learn more below about the possible reasons why your car hesitates when you try to accelerate.
How do you fix loss of power when accelerating? ›
6 possible reasons why your car's losing power when accelerating
- Solution: replace your spark plugs, or see a mechanic about your ignition coil.
- Solution: clean your car's air filter, or get your oxygen sensor checked by a mechanic.
- Solution: replace your car's fuel filter, or see a mechanic about a blocked exhaust.
If your engine revs up as you press down on the gas but your vehicle doesn't accelerate as much as you'd expect, you may be dealing with transmission slipping. If you've ever tried to accelerate on ice, where your engine revs but your vehicle goes nowhere, you know the feeling.
Why do I have to press hard on my gas pedal to accelerate? ›
Most common cause of poor throttle response is a dirty throttle body. You could try having the throttle body cleaned as well as the mass air flow sensor. Also have the engine computer checked for any faults. The throttle body and mass air flow sensor are the two most common causes for poor throttle response.
