Has anyone experienced gear shift jerking after just replacing the spark plugs and cleaning the throttle? It was fine for two or three days, but then the jerking returned.

After a major maintenance on the 2006 Accent 1.4 manual, the spark plugs, carbon canister solenoid, and throttle have been replaced, and the fuel injectors have been cleaned. With the fuel price at 7.91, it's costing 0.9 per kilometer. Is this normal? The oxygen sensor is fine!

The Kia Sportage has a jerking sensation when shifting gears.

The engine fault code flashes at idle and stays on when starting. The fault indicates a misfire in cylinder two. After replacing the ignition coil and spark plugs, and cleaning the injectors, the fault code disappeared but returned after two days. Do you know what might be causing this?

What could be the reason for a vehicle with an 8-speed automatic transmission to jerk when shifting from 3rd to 2nd gear?

I have a 2015 2.0L automatic model, the second highest trim without a sunroof. The fuel consumption is at 9, which seems quite high. Last year, I had a maintenance check where the throttle body was cleaned, and the spark plugs were replaced. Tires are fine too. The fuel consumption is terrifying—almost 0.7 currency per kilometer. Why is it so high?

The car stopped in the middle of the road, with 25,000 km mileage. Couldn't shift gears, and the clutch felt heavy. Surprisingly, it was fine the next day. Decided to replace the clutch slave cylinder for 240 RMB. 🤷‍♂️

What should I do about the gear shifting impact in the Yuexiang when it's fine when cold but jerks when hot?

Hello fellow car enthusiasts! I'm having an issue with my car and would like to seek your advice. The check engine light is on, and it's hard to start the car (it takes a while to start). Once it starts, the RPM is normal, but as soon as I shift gears, the RPM immediately jumps to over 1000, almost 2000. When I shift back to Park, the RPM slowly returns to normal. I've already replaced the throttle, and it worked fine for two days, but now the same problem is back. Has anyone else encountered this? What could be the issue?

Does your Jetta automatic also have a noticeable jerk when shifting gears?
