car shakes when accelerating but not when coasting

If you’ve ever been driving and noticed that your car starts shaking when you press the gas pedal, but not when you’re coasting, you might be wondering what’s causing the problem. Luckily, there are a few potential explanations for this phenomenon. Keep reading to learn more about car shakes when accelerating but not when coasting.

Explore the possibilities

  • One possibility is that your car’s engine is misfiring. This can happen for a number of reasons, including a dirty air filter or a problem with the spark plugs. If your car’s engine is misfiring, it’s important to get it checked out by a mechanic as soon as possible, as it can cause long-term damage if left unaddressed.
  • Another possibility is that your car’s tires are out of balance. This means that the weight of the tire is not evenly distributed around the circumference of the tire. This can happen over time as tires wear down. If your car’s tires are out of balance, you’ll need to take it to a tire shop to have them rebalanced.
  • Finally, it’s also possible that your car’s wheels are crooked. This can happen if you hit a pothole or curbs too hard. Crooked wheels will cause your car to pull to one side while you’re driving and can also cause shaking while accelerating. If your wheels are crooked, you’ll need to take your car to a mechanic or a tire shop so they can be realigned.

Other issues associated with your car shaking

While a shaking car can be caused by something as simple as a loose wheel, it can also be a sign of a more serious problem. If your car begins to shake, it is important to have it checked by a qualified mechanic as soon as possible.

Depending on the cause of the shaking, it may be necessary to have your car’s suspension system or tires replaced. In some cases, a shaking car may indicate that the engine is misfiring or that the wheels are out of alignment.

Why you need to address these issues quickly

If left unaddressed, these problems can lead to decreased fuel efficiency, reduced handling, and increased wear and tear on your car’s components. By having your car checked by a professional, you can ensure that any potential problems are resolved before they cause further damage.

So, if your car is shaking when you accelerate, don’t wait to get it checked out. Bring it to a mechanic or a tire shop so they can diagnose and fix the problem.


If your car shakes when you accelerate but not when you’re coasting, there are a few potential explanations. It could be something as simple as dirty spark plugs or an imbalance in your tires. However, if the problem is more serious, such as crooked wheels, it’s important to get it fixed by a professional as soon as possible.
