If during acceleration the car starts to twitch, then it is quite obvious that something is wrong with the car. The problem lies mainly in the fact that there are a great many reasons for "jerking" during acceleration. Today we will focus on the five most common and relevant of them.
1. Low-quality fuel
Low-quality gasoline is the source of many troubles and problems in the car, including kicks during acceleration. All this is another convincing reason to find a gas station where employees are responsible are suitable for checking and maintaining filters through which fuel from tanks passes into dispensers and pistols.
2. Power plant supports
The strongest shocks can also cause the supports that have been loosened over the years, on which the power unit is fixed. More often than not, the engine just vibrates harder. However, in really advanced cases, the unit may also start to "ride" back and forth when accelerating and decelerating.
3. Engine sensors
Kicks of the car during acceleration can even be triggered by the breakdown of individual car sensors. The most common culprit is the throttle position sensor as well as the MAF sensor. In this case, the "Check Engine" light may even come on.

4. Lack of oil
This problem only applies to vehicles with an automatic transmission. Modern transmission models are extremely sensitive to dropping lubricant levels. If it falls at least 0.5 liters from the permissible minimum, the same jerks and jerks may begin during acceleration. In such a situation, the most important thing is to identify the source of the leak in time.

5. Overheating of the transmission
Finally, jolts during acceleration can be caused by overheating of the transmission. This happens when the motorist forgets to periodically change the working fluid in it, as well as clean the transmission radiator.
