In your case, the jerking you are experiencing is likely due to the fuel pressure sensor. When the fuel pressure is too low, the engine will not be able to get enough fuel, which will cause it to jerk. When the fuel pressure is too high, the engine will get too much fuel, which will also cause it to jerk.
If you are experiencing jerking, hesitation, or stalling, it is important to have your fuel pressure sensor checked. A bad fuel pressure sensor can cause a number of problems, so it is important to get it fixed as soon as possible.
Here are some other symptoms of a bad fuel pressure sensor:
* Engine stalls when idling
* Engine hesitates when accelerating
* Engine runs rough
* Check engine light comes on
If you are experiencing any of these symptoms, it is important to have your fuel pressure sensor checked.
