What causes the jerky feeling of insufficient fuel supply in a car?
1 Answers
Reasons for jerky acceleration and fuel cut-off are as follows: 1. Engine power supply system: Spark plugs and ignition coils. If the high-voltage spark is weak, it can cause intermittent engine malfunction. 2. Engine fuel supply system: Fuel injectors. If the injectors have carbon deposits, slight blockages, or poor atomization, it can easily lead to abnormal fuel injection. 3. Valve body damage: Transmission issues such as jerking, hesitation, or gear hunting are usually caused by a damaged valve body or dirty transmission fluid with internal impurities. Especially when dirt and impurities accumulate inside the valve body, blocking the passages, it prevents effective regulation of oil pressure, leading to jerking, slipping, and other problems. 4. Damaged engine mounts: If the transmission mount is damaged, it fails to provide cushioning when releasing the throttle, resulting in jerking. 5. Excessive carbon buildup: If the throttle body is not cleaned for a long time, excessive carbon deposits can alter the throttle opening angle, causing jerking when releasing the throttle.
