1. Ignition Issues: A faulty spark plug or ignition coil can cause the engine to misfire, resulting in a jerking motion and power loss. Check the ignition system components and replace any defective ones.
2. Fuel Delivery Problems: A clogged fuel filter or injector can restrict fuel flow to the engine, causing it to jerk and lose power. Check the fuel system components and clean or replace any clogged parts.
3. Transmission Problems: A slipping transmission can cause the car to jerk and lose power when shifting gears. Have the transmission fluid level checked and make sure it's at the proper level. If the fluid is low, top it off and check for leaks. If the fluid is at the proper level, you may need to have the transmission serviced or repaired.
4. Vacuum Leaks: A vacuum leak can cause the engine to run lean and jerk or lose power. Check the vacuum hoses and connections for any leaks and replace any damaged or loose hoses.
5. Catalytic Converter Issues: A clogged or damaged catalytic converter can restrict exhaust flow and cause the engine to jerk and lose power. Check the catalytic converter and replace it if necessary.
If you are experiencing these symptoms, it's recommended to have your vehicle diagnosed by a professional mechanic to determine the exact cause and get the appropriate repairs done.
