How to Solve Car Jerking?
2 Answers
Car jerking can be resolved by: 1. Checking the temperature of the transmission and its cooling system; 2. Replacing the transmission fluid; 3. Inspecting the internal valve body of the transmission for damage that may require replacement; 4. Checking the engine valves and intake pipes for carbon buildup that needs cleaning. The causes of car jerking include: 1. Clogged engine oil passages; 2. Dirty transmission fluid clogging the oil passages; 3. Damaged transmission solenoid valve; 4. Forgetting to release the handbrake; 5. Irregular wear of the clutch; 6. Damaged solenoid valve; 7. Engine cylinders not working properly; 8. Poor quality fuel with low volatility.
I've experienced quite a few cases of car jerking. If the car stutters while driving, it's mostly due to ignition system issues, such as excessive carbon buildup on the spark plugs or incorrect gap. First, check the spark plugs yourself—take them out and see if they're blackened or worn. Replacing a set isn't expensive. Or, if the air filter is too dirty and blocks the intake, the engine struggles with airflow—just replace the air filter. The fuel system could also be the culprit, like clogged fuel injectors or unstable fuel pressure. Try adding some fuel additive to clean the tank. For manual transmission jerking, the clutch disc might be worn—replacing it requires some effort. Safety first—if the jerking persists, take it to a repair shop to check the transmission or ECU. Don't let it turn into a major problem.
