1. Low transmission fluid: If the transmission fluid is low, it can cause the transmission to slip, which can lead to jerking. Check the transmission fluid level and add more if necessary.
2. Faulty transmission: A faulty transmission can also cause jerking. If the transmission is not shifting properly, it can cause the car to jerk when going up hills. Have the transmission inspected by a qualified mechanic if you suspect it may be faulty.
3. Dirty fuel injectors: Dirty fuel injectors can cause the engine to run rough, which can lead to jerking. Clean the fuel injectors or have them cleaned by a qualified mechanic.
4. Faulty spark plugs: Faulty spark plugs can also cause the engine to run rough, which can lead to jerking. Replace the spark plugs if they are worn or damaged.
5. Vacuum leak: A vacuum leak can cause the engine to run lean, which can lead to jerking. Check for vacuum leaks and repair any that you find.
6. Faulty oxygen sensor: A faulty oxygen sensor can cause the engine to run rich or lean, which can lead to jerking. Replace the oxygen sensor if it is faulty.
7. Clogged catalytic converter: A clogged catalytic converter can cause the engine to run poorly, which can lead to jerking. Have the catalytic converter inspected by a qualified mechanic and replace it if necessary.
