A car may jerk due to several reasons, including issues with the fuel system, such as a clogged fuel filter or failing fuel pump, which can disrupt the flow of fuel to the engine. Additionally, problems with the ignition system, such as worn spark plugs or faulty ignition coils, can cause misfires that lead to jerking. Transmission issues, such as low fluid levels or a slipping clutch, can also result in a jerky driving experience. Regular maintenance and prompt attention to warning signs can help prevent these problems.
