1. Air bubbles in the fuel line: When refueling, air can sometimes enter the fuel line. This air can cause the car to jerk as the engine tries to draw in fuel but gets air bubbles instead. The air bubbles will eventually work their way out of the line, but in the meantime, they can cause the car to run rough.
2. Dirty fuel filter: A dirty fuel filter can restrict the flow of fuel to the engine, which can also cause the car to jerk. The fuel filter should be replaced as recommended in your car's owner's manual.
3. Faulty fuel injector: A faulty fuel injector can spray too much or too little fuel into the engine, which can also cause the car to jerk. Fuel injectors should be cleaned or replaced as needed.
4. Faulty throttle position sensor: A faulty throttle position sensor can provide the engine with incorrect information about the position of the throttle plate, which can cause the car to jerk. The throttle position sensor should be replaced as needed.
If you experience your car jerking after putting in gas, it's important to have it diagnosed by a qualified mechanic as soon as possible to prevent further damage to the engine.
