Why Does Your Car Jerk When Accelerating?

When dealing with car problems, one needs to consider a series of possible areas where the problem might generate from. A major example is when you get a burning smell from your car.

This could be as a result of a lose hose under the hood coming in contact with a hot area on the engine, oil leakage spilling on hot engine parts or maybe even a short circuit in the electrical parts of the car. While these parts don’t really seem related, they all need to be checked out to be sure.

The same goes for when your car jerks while accelerating. Your car could do so for a number of reasons explained thus;

 

 

Possible Reasons Why Your Car Jerks When Accelerating

 

1). Polluted Injection System, Fuel Filter or Fuel Tank :

Pollution in any of these parts could lead to an insufficient supply of fuel into the engine which in turn would call your car to jerk.

The engine consumes a certain of dosage at each rev or each time you use the throttle. During this period, the spark plug fires and needs a bit of fuel to create an explosion that moves the pistons in the cylinder.

If there is no supply of fuel for a few seconds due to the blockage from the dirt, it could cause the engine to misfire and then jerk as if it has run out of fuel, but then come back alive immediately the supply is back on.

On a technical note, it is not that hard to fix. All you need is a special cleaning kit solely for injectors which happens to be quite cheap. You should use them on a regular basis, given how the common saying goes about prevention being better than cure.


2). Polluted Fuel Pipes :

Fuel pipes are tasked with the aim of transferring fuel from one section of the engine to another. Just as explained previously, any disruption in this transfer can make the engine jerk while accelerating. This also leads to other issues mostly affecting the internal combustion of the engine.

3). Spark Plug Problems :

The spark plug has to be kept neat always because the engine needs sparks from it at every rev in order to accelerate. If the head of the spark plug is rusty or faulty and cannot deliver sparks as needed, you might need to completely change it to prevent this problem from further complicating the overall well being of the vehicle.

Changing the spark plug in this case is better compared to removing it and scraping the top with some metal hoping it comes back to life. Vehicles will reciprocate whichever treatment you give them to you on worse days, so, be nice.


4). Wrong Wheel Alignment :

Sometimes, the problem isn’t with the engine, the delivery of the fuel or the internal combustion from the spark plug. Your car might as well be reacting badly to pulling. This is much more manifested as your car moving slow rather than actually jerking, but all the same, you need to have the tires checked.

More specifically, you need to check the pressure in the tires. It could just be getting worse from a traumatic experience you previously had. If this happens while you’re on the highway and no one to help, an inflator product would come in handy.

After leveling up, you need to get the car to a mechanic as soon as possible to get the tires aligned.


5). Moist Distributor Cap :

This part of the car is very easy to ignore because when explained to a less experienced people, it doesn’t seem relevant to the problem. The cold weather is to be blamed in this case.

If you park your car in the cold, mostly during the winter periods, your car has a huge tendency to accumulate moisture. This could lead the engine to misfire occasionally and then jerk when accelerating.

The simple solution in this case is to always park your car in a warm place during the cold season, preferably inside your garage.


6). Damaged Carburetor  :

The job of the carburetor is to mix the right amount of air and fuel needed for the engine to have an appropriate fuel combustion. If the carburetor is faulty, the entire process is jeopardized and this directly influences the performance of the car.

It basically has the same effect as a dirty fuel filter or contaminated fuel tank. So, if you suspect a fault in the combustion area as the reason for your car jerking when accelerating, check all the related parts all together.

 

Conclusion

Other causes could be poor engine tuning, an error in the motor winding, or blockage in one of many parts of the vehicles’ engine. To save yourself the trouble, it’s best to have a certified auto mechanic inspect the vehicle as they tend to understand which symptoms are particular to which parts and figure out the problem more quickly.
