What would cause a car to jerk while driving?
Hi,
I have a Hyundai Accent GVS 1.4 Petrol version car (2004 manual transmission model).
Recently while i was driving back home, the car starting jerking when I slowed down and accelerated back. It jerked once and sometimes a couple of times, every time i slowed down and accelerated and then would go steady. Previously when I slowed down to the same speeds in same gear positions this never happened.
I have checked the speed vs rpm ratio and there is no change as compared to previous readings I collected.
I had got a new fuel pump about 6-8 months back.
What would be the problem and what is the suggested fix???

I didn't see any mention of a possible problem with the torque converter clutch (TCC) not disengaging when slowing down.
There could be a few reasons for that , but if all the other suggested checks don't produce anything, the TCC is a good area to investigate.

- Engine misfire: An engine misfire can cause the car to shake and judder. It can be caused by various factors, such as faulty spark plugs, ignition coils, or fuel injectors.
- Transmission issues: A malfunctioning transmission or torque converter could cause the judder when accelerating. This can result from worn-out components or problems with the transmission fluid.
- Suspension problems: Faulty or worn-out suspension components can cause excessive bouncing or vibrations, particularly when encountering bumps or uneven road surfaces.
- Transmission response: If the transmission is slow to engage or shift gears, it may cause a delay in acceleration. This could be due to issues with the transmission fluid, solenoids, or sensors.
- Throttle response: In some cases, a delay in throttle response can be caused by a problem with the electronic throttle control system or throttle position sensor. It's worth having these components checked and tested.
Providing them with detailed information about your car's symptoms, along with any records or documentation from previous inspections, can assist in their investigation. They may need to perform further diagnostic tests, such as checking for error codes, conducting a thorough transmission inspection, or examining the suspension components, to pinpoint the exact cause of the problems you're experiencing.
Remember to keep all communication with the dealer and any repair shops documented, as it may be helpful if you need to escalate the issue or refer to it in the future.
