One of the most common reasons of your car jerking as you accelerate is a possible blockage in its engine. If you don’t remove that blockage, your car will continue to jerk because gasses are not coming out of it when they are supposed to. You will know that this is the case when the “Check Engine” light in your car is on.
Don’t ignore that light, especially when it is blinking. Aside from jerking as you accelerate, you will notice that your gas level could easily go low. At this point, I will suggest to call a professional to remove the blockage. If you don’t act on it quickly, you will gas and that is just wasting your money.
Check the fuel filter for dirt because that might be the reason your car is acting up. If you haven’t clean that area of your car, then there is a huge possibility that dirt has already built up in there. All you need to do it wipe those off and check if your car would do jerk again as you accelerate. For interior car cleaning it is good to use powerful car vacuum cleaner.
This is one of the most neglected parts of the car, the injectors. You will know this is the case when your car completely loses its power.
It is also a symptom when your car not only jerks but if you see your engine firing something out there while you are driving, then your car’s injectors are definitely messed up. The truth is that it’s not that serious to fix it. You don’t even need to hire someone.
