* Clogged fuel filter: A clogged fuel filter can restrict the flow of fuel to the engine, causing it to run lean and jerk.
* Dirty mass air flow (MAF) sensor: A dirty MAF sensor can provide the engine with incorrect air/fuel mixture data, which can lead to jerking.
* Faulty oxygen sensor: A faulty oxygen sensor can cause the engine to run rich or lean, which can lead to jerking.
* Transmission problems: A slipping transmission or a faulty torque converter can also cause jerking.
* Engine vacuum leaks: Vacuum leaks can cause the engine to run lean and jerk.
If you are experiencing jerking in your Opel Vectra B 2.0, it is important to have it diagnosed and repaired by a qualified mechanic as soon as possible to prevent further damage to the vehicle.
