What Causes Jerking During Acceleration?
2 Answers
Car jerking during acceleration is caused by engine oil passage blockage. Detailed causes and solutions for car jerking during acceleration are as follows: Detailed Causes: Engine oil passage blockage; Dirty transmission oil clogging oil passages; Damaged transmission solenoid valve; Forgetting to release the handbrake; Irregular wear of the clutch; Damaged solenoid valve; Some engine cylinders not working; Poor volatility of low-quality fuel. Solutions: Check the transmission temperature and cooling system; Replace transmission oil; Inspect the internal valve body of the transmission for damage that may require replacement; Check the engine valves and intake pipe for carbon buildup that needs cleaning.
Starting hesitation sounds frustrating, and I've experienced it with my manual transmission car. There are several possible causes. Clutch slippage is the most common issue, especially in older manual cars where worn clutch plates can make the car feel stuck or shaky during takeoff. For automatic transmissions, oil pressure problems or transmission computer control errors can cause delayed response, like not accelerating promptly when pressing the gas pedal. Ignition system failures are also frequent, such as carbon buildup on spark plugs leading to uneven fuel combustion and hesitation. Fuel system blockages can cause insufficient supply during acceleration, resulting in similar symptoms. Don't underestimate it—delaying inspection may lead to engine damage. Start with simple checks first, like verifying gear and throttle synchronization, and ensure regular transmission fluid changes.
