I have replaced the fuel pump already. The vehicle jerks while in motion but not all of the time. The vehicle has shut off while being driven down the road but starts right back up. The oil light is the only thing that is on when it shuts off. Does not do it all the time, seems to be intermittent. Please Help!!
Hi there.
A car that jerks when starting it, when accelerating or whilst you're driving is showing symptoms that something is wrong, though there can be many causes: it can be problems in the starting system, fuel, engine or the exhaust pipe. You may even notice that your car engine light has come on to warn you of a problem. Getting to the problem at the first symptoms can avoid more serious break-downs. In one HOWTO we'd like to give you some advice so you know all the possible reasons and answer your question: why is my car jerking?

Symptoms
For more extended information, take a look at our article on the symptoms of a blocked catalyst. The best you can do if your car is jerking due to a blocked catalyst is to visit a trusted mechanic to fix it.
Jerking caused by a fault in the spark plug
Another cause for jerking can also be a fault in the spark plug or one of its cables. You will know this is the case if your car jerks when you start it in the morning. The symptoms are very similar to a blocked catalyst, but if it's a problem with a spark plug, you'll notice the following too:
Symptoms
In this case, you can solve the problem yourself by changing the spark plug. If you don't have the skills to change the spark plug yourself make sure a professional solves this problem.
It is very important to keep the spark plug clean, so you can avoid car jerking and other more problems.
Car jerking because of a drained acceleration cable
A car jerking can also be a result of the acceleration cable being very worn out. You will notice because of the following symptoms apart from the jerking:
Symptoms
The best you can do is change it as soon as possible, as the car will stop at any moment if you leave it to break. Take the vehicle to a mechanic to solve the problem. If your car has this problem, take a look at our article to know all the reasons why your car jerks when accelerating to find out what it may be or try adjusting the acceleration cable if you are handy with cars.
Symptoms
It's best to clean them regularly to avoid costly reparations. You can do this yourself using a specific cleaning kit, which are quite cheap and can be found almost everywhere.
Car jerking because of the motor winding
The car's engine/motor winding can be another reason for car jerking. Wear of the engine's winding is most likely caused by the engine being put under stress - i.e. through hard acceleration.
Symptoms
The only way of knowing if this is the case is through the use of an Ohm meter, so if you don't own one it's best you check with a mechanic to know if this is the reason your car is jerking.
These are the most common causes of a car jerking, however, your car could have another problem that needs the help of a specialist. If you're not sure of what is happening to your car it's better to bring it to a mechanic. The specialist will find the root of the problem.

the valve cover gaskets were leaking oil around the spark plug boots making the boot swell and causing a voltage leak. the engine misfired and stop lights. i did a tune up with new cover gaskets,plugs, wires, cap and rotor and she runs like a top. vrooom, vrooom!!

Had the same problem with my 2004 lx 2.7, code reader said cam position sensor, replaced that $30 @ autozone. 2 screw on front of engine, easy fix and no more jerking
